I'm trying to send an email in c. I want to use libcurl for that. But before i need to understand how it's working.
So i download curl-7.63.0.zip and MinGW32.
After installing MinGW, i select all the basic package :
mingw-developper-toolkit-bin
mingw32-base-bin
mingw32-gcc-fortran-bi
mingw32-gcc-g++-bin
mingw32-gcc-objc-bin msys-base-bin
In next, i have extracted all the files to a folder and i run a cmd to write
\>cd "something\curl-7.63.0"
\>mingw32-make mingw32-ssl
But i recieve an error :
\>D:\Projets_Info\Emails\Méthode n°8 Libcurl\drivers\curl-7.63.0>mingw32-make mingw32-ssl
mingw32-make -C lib -f Makefile.m32 CFG=mingw32-ssl
mingw32-make[1]: Entering directory 'D:/Projets_Info/Emails/Méthode n°8

Makefile:61: recipe for target 'mingw32-ssl' failed

Does anyone has an idea ? An idea that permit me to have curl with ssl

I added iptables package to my device image, using CORE_IMAGE_EXTRA_INSTALL += "iptables".
I tried to run it on the device and get the following error message:
modprobe: FATAL: Module ip_tables not found in directory /lib/modules/4.9.11-1.0.0+gc27010d
iptables v1.6.1: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
Seems like I have missing kernel module.
Need your help in adding standard kernel module to the image (Where can I find all modules files and how should I add and load it to the image).
You must add the iptables module to your kernel. I had the same problem and I could solve it with these steps:
Run bitbake -c menuconfig virtual/kernel
Activate CONFIG_IP_NF_IPTABLES module (you can search its location on that menu typing slash '/').
Save it and run bitbake -c savedefconfig virtual/kernel for saving that file as a defconfig.
Copy defconfig file from returned path to yocto-distro/layer-name/recipes-kernel/linux/files/ (make this directory if it does not exist).
Create a .bbappend file inside yocto-distro/layer-name/recipes-kernel/linux/ with the same name as your original recipe file from meta layer.
Edit your file and append lines below:
SRC_URI += "file://defconfig"
KERNEL_DEFCONFIG = "${WORKDIR}/defconfig"
FILESEXTRAPATHS_prepend := "${THISDIR}/files"
~
Relaunch bitbake your-image-name
It worked on my situation. Btw, I got that info from the following webs:

Have a nice day! :D
I've been compiling OpenSSL (and thus Perl >5.10, as it is a dependency) on multiple platforms. I've managed to get 1.1.0b compiled on every single platform except AIX, which I can't even compile Perl. I've tried several versions and looked at the documentation Perl provides online. From what I can tell, it suggests version 5.12.2.
When I attempt to compile version 5.12.2,
I take the following from the documentation, and fill in a few local system variables, such as using XLC rv7.
export OBJECT_MODE=64
./Configure \
-d \
-Dcc=/usr/vac/bin/xlc_r7 \
-Duseshrplib \
-Duse64bitall \
-Dprefix=`pwd`/../PERL
Then I attempt to make as prompted, and get the following error:

Taking a look at pod/perlmodlib.PL, we see the following:

# filenames will work.

In my desperation I tried to hack it up and avoid writing to the manifest, but then I get this issue:

The frequency of errors makes me feel like perhaps I don't have something configured right...
My next thought was to try the most updated version, which at the time of writing is 5.24. Using the same configuration and attempting to make I get the following issue:
Can't locate strict.pm in #INC (you may need to install the strict module) (#INC contains: /cpan/AutoLoader/lib /dist/Carp/lib /dist/PathTools /dist/PathTools/lib /cpan/ExtUtils-Install/lib /cpan/ExtUtils-MakeMaker/lib /cpan/ExtUtils-Manifest/lib /cpan/File-Path/lib /ext/re /dist/Term-ReadLine/lib /dist/Exporter/lib /ext/File-Find/lib /cpan/Text-Tabs/lib /dist/constant/lib /cpan/version/lib /lib .) at autodoc.pl line 25.

make: The error code from the last command is 2.
Which I know from other compilations means I need to edit the PERL5LIB variable.
If I keep adding all the modules to the path:
export PERL5LIB=`pwd`/dist/Exporter/lib:$PERL5LIB
export PERL5LIB=`pwd`/cpan/Text-Tabs/lib:$PERL5LIB
export PERL5LIB=`pwd`/ext/re:$PERL5LIB

export PERL5LIB=`pwd`/dist/PathTools/lib:$PERL5LIB
export PERL5LIB=`pwd`/ext/File-Find/lib:$PERL5LIB
Even so, I'll still get an error for a module that isn't even present in the 5.24.0 source!

I have MakeMaker, but the 5.24 version does not contain vpp.pm! Again, in desperation I attempted to put it in there from a different source, and I get this error:

make: The error code from the last command is 2.
All of this makes me feel like perhaps I'm not configuring something right... Can anyone with some experience help me out with some cut and dry installation instructions for Perl on AIX? I'd be super grateful. Thanks!

I pull down and compile openssh and openssl frequently. I use gcc and no real magic that I can recall.
Here is my script to build it. I don't know which perl is native to AIX but it seems to work for me.

I'm linking to a library on my filesystem using ld.
When I run the command ld -verbose -lmylib, I get the following back:
attempt to open /usr/x86_64-linux-gnu/lib64/libmylib.so failed

ld: cannot find -lmylib
I'm confused as to why it's trying to open files prefixed with //. This is not the case for another computer of mine. I've tried changing LIBRARY_PATH, LD_LIBRARY_PATH, my PATH, etc. but nothing seems to work. I've looked online, but can't find anything. Where are these paths set?
Thanks.
The problem here is you are trying to link against the library mylib, but this library is not in the system's library search path, or it does not exists at all. You please make it locate at the right place. If the library is in another directory that is not in the library search path, you can add it with -L option to ld, like ld -verbose -L<the directory> -lmylib.
As for the double slash you see, it's not a problem, as more than more slashes are interpreted as one slash on Linux, that is to say, //foo/bar is the same as /foo/bar`, so don't need to worry about it.
As for the difference of the search path, on Fedora, the default search path is:
SEARCH_DIR("/usr/x86_64-redhat-linux/lib64"); SEARCH_DIR("/usr/lib64"); SEARCH_DIR("/usr/local/lib64"); SEARCH_DIR("/lib64"); SEARCH_DIR("/usr/x86_64-redhat-linux/lib"); SEARCH_DIR("/usr/local/lib"); SEARCH_DIR("/lib"); SEARCH_DIR("/usr/lib");
While on Ubuntu, it is:
SEARCH_DIR("/usr/x86_64-linux-gnu/lib64"); SEARCH_DIR("=/usr/local/lib/x86_64-linux-gnu"); SEARCH_DIR("=/usr/local/lib64"); SEARCH_DIR("=/lib/x86_64-linux-gnu"); SEARCH_DIR("=/lib64"); SEARCH_DIR("=/usr/lib/x86_64-linux-gnu"); SEARCH_DIR("=/usr/lib64"); SEARCH_DIR("=/usr/local/lib"); SEARCH_DIR("=/lib"); SEARCH_DIR("=/usr/lib");
So Ubuntu start each path with prefix '=', now let's see what ld does for this:
If searchdir begins with "=", then the "=" will be replaced by the sysroot prefix, controlled by the --sysroot option, or specified when the linker is configured.
That means = will be replaced by system root, which most like is / for a Linux system. That's why you see the double slashes on Ubuntu not on Fedora.
I want to use a webservice in C code. I am trying to make a client. I need something to do what Axis2java does and generates the classes from a wsdl files.
I found that Axis2c makes (.c) files generated from wsdl file.
I downloaded it from here . unzipped it. I created the environment variable for AXIS2C_HOME and I created AXIS2C_CLASSPATH.
but I can't make it work.
when I type this command :
WSDL2C -uri -ss -sd -d none -u -f -o
I get this error :
echo off
Error: Could not find or load main class org.apache.axis2.wsdl.WSDL2C
how can I solve this problem. and please tell me how to use this Axis2c tool properly.
Thank you in advance.
#loentar : I installed Axis2/Java and I set the environment variable for it. now I run the wsdl2c.bat I get this :

after that I run this command :
E:\dev\Tools\axis2c-bin-1.6.0-win32\bin\tools\wsdl2c>WSDL2C.bat -uri hello.wsdl
-u -uw

what can I do ?
I'm using windows 8 by the way.
In addition to Axis2/C you must have Axis2/Java installed.
AXIS2_HOME must point to Axis2/Java installation.
For details please see README of codegen.
The complete list of commands to create and compile client is:
# create stubs
sh $AXIS2C_HOME/bin/tools/wsdl2c/WSDL2C.sh -uri Calculator.wsdl -u -uw
# implement main() in src/your_client.c
# see samples/codegen/client/calculator for example
# compile and link client
gcc -o calculator_client src/*.c -I$AXIS2C_HOME/include/axis2-1.6.0 -L$AXIS2C_HOME/lib -laxutil -laxis2_axiom -laxis2_parser -laxis2_engine -lpthread -laxis2_http_sender -laxis2_http_receiver -ldl -Wl,--rpath -Wl,$AXIS2C_HOME/lib
I set the envinroment variable for JAVA_HOME, AXIS2_HOME, AXIS2C_HOME, and added their lib folder to CLASSPATH. after running this command:
WSDL2C.bat -uri hello.wsdl -u -uw
I got this message:
echo off
Error: Could not find or load main class org.apache.axis2.wsdl.WSDL2C
I found the solution myself. :)
I double checked if I had created the environment variable for AXIS2_HOME and I saw that it is there, correctly.
in spite of it's existence I tried to set it again in command prompt. so I typed:
SET AXIS2_HOME=E:\dev\Tools\axis2-1.6.2
then I typed the command for WSDL2C code generator:
WSDL2C.bat -uri hello.wsdl -u -uw
And BAM ! it worked properly.
Now I can generate C files from WSDL file.
I'm working with net-snmp C API , i create a MIB file ( containt a table of information ).
After that i used the mib2c that gives me two file "myproject.h" and "myproject.c"
I copy this two files in the directory : /net-snmp/agent/mibgroup
and i compile like this :
1) ./configure --with-mib-modules=myproject
2) make
3) sudo make install
and from a terminal i run this command : snmpd -f -L -Dmyproject
and i get the message below : registered debug token myproject,1
Turning on AgentX master support
NET-SNMP version 5.7.2
My question is :
that when i try to run snmptable for this table i get the messsage : NO ENTRIES
and when i try to make snmpset to this table : i get this massage
Error in packet. Reason: notWritable (That object does not support modification)
*NOTE : in my file myproject.c i followed the example given by the net-Snmp :data_set.c
http://www.net-snmp.org/dev/agent/data__set_8c-example.html
but my table has not been initialisated
please i need help
thanks in advance
thanks K1eran for your reply .
the problem that i have it's not because of a badcommunity , here is my community configuration in the file of snmpd located in /usr/local/share/snmp:
full access from the localhost
rocommunity public localhost
rwcommunity private
really i don't know what is the problem ?
Possibly related to community strings i.e. snmpset's -c flag . It would be better to see details of snmpset and snmptable commands however as described at :
net-snmp snmpset tutorial ...
Note that if you don't have write permission to the object ...
% snmpset -v 2c -c badcommunity test.net-snmp.org ucdDemoPublicString.0 s "hello"
Error in packet.
Reason: notWritable
`
In snmpd.conf file the "#rocommunity public localhost " default settings will be commented(meaning localhost public not permitted read/write),
so
UnComment the "rocommunity public localhost" and change to "rwcommunity public localhost" then restart the snmpd service and check
