I'm trying to link an external library but not linking. Using gcc version:
gcc (MinGW.org GCC Build-2) 9.2.0
Windows 10
Command I'm tried:
gcc -g test.c -Wall -I ../inc/ -L ../lib -l:libFp.a -o test.exe
gcc -g test.c -Wall -I ../inc/ -L ../lib64 -l:libFp.a -o test.exe
gcc -g -Wall -I ../inc/ -L ../lib -l:libFp.a test.c -o test.exe
gcc -g -Wall ../lib/libFp.a test.c -I ../inc/ -o test.exe
Error:
c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: C:\Users\XXXXXXXX\AppData\Local\Temp\cciWnORn.o: in function `main':

Tried different solutions from StackOverflow but still same error.
Update: gcc -g -Wall -I ../inc -L ../lib test.c -o test.exe -lFp -Xlinker --verbose command output
Linker Output Verbose

I run it on Linux with x86/64 and ubuntu 2204, gcc version 11.2.0, GNU ld version 2.38.
When I run env LIBLEVELDB=/usr/local make in simpleleveldb dir and get this error:
cc -I. -I../simplehttp/.. -I/usr/local/include -I/usr/local/include -Wall -g -O2 -MM -MT simpleleveldb -MF simpleleveldb.deps simpleleveldb.c str_list_set.c

collect2: error: ld returned 1 exit status
make: *** [Makefile:26: simpleleveldb] Error 1
before do it I just build simplehttp follow this repo https://github.com/bitly/simplehttp.
Anyone has some idea? thanks!
I'm trying to compile a simple project with .c and .s files using my Mac.
When I run 'make' it goes threw on the compilation, and I think it failed when its trying to link (not sure).
Here is the error it shows:
gcc -m32 -g -Wall -c -o main.o main.c
gcc -m32 -g -Wall -c -o numbers.o numbers.c

and I'll add the makefile as well:

I am trying to install the C binding for ZooKeeper while ssh'ed to another computer using a build system: i386-pc-solaris2.11 (I don't know if that is important). Anyways, the computer I ssh'ed to is running a linux based OS.
I ran the following code in the command line:
cd ../zookeeper
cd src
cd c
./configure
make
The terminal inputs above were taken from the Apache website for setting up the C shell client. The error code I am getting is originates from the make:
libtool: link: ( cd ".libs" && rm -f "libzookeeper_mt.la" && ln -s

cli_mt:localhost:2181 does not work as the ZooKeeper library is not installed in /usr/local/lib . I do however have zookeeper working in the C client on my local computer, I just need it working on this system.
Please help, this is just the installation of zookeeper on a linux computer. I don't understand linux too well, nor do I understand the error code given to me from this makefile.
EDIT: I figured out that I do not have permissions to change the /usrs/local/lib directory on this server. I tried
distclean && ./configure --prefix=/workspace/kunalp/zookeeper/ --libdir=/workspace/kunalp/zookeeper/lib && make install
to relocate the library directory. This however did not fix the problem, giving me the following error:
/bin/sh ./libtool --tag=CC --mode=link gcc -DTHREADED -g -O2 -

Thanks
The Solaris compiler does not have __sync_fetch_and_add. To fix this I had to find an equivalent function in the Solaris compailer: atomic_add() and replace __sync_fetch_and_add with atomic_add() in mt_adaptor.c. This fixed my make command
/usr/bin/gcc -DEVAL -std=c11 -O2 -pipe -static -s -o Tutorial Tutorial.c -lm
this command line (right on linux) don't run on macOS,
How can i change this command line?
UPDATE: the command line that doesn't work is
gcc -DEVAL -static -std=c11 -O2 -pipe -s -o main.out $1 -lm -g
I have a file test.pyx and a test.c generated by $ cython test.pyx. I want to create a shared object test.so with gcc so that I can import it into Python. Compilation for linux x86-64 with
gcc -Wall -fPIC -I /usr/include/python2.7 -shared -o test.so test.c
Terminates successfully.
I want to compile the same file to a .dll for windows with mingw32. However when I attempt to execute
i586-mingw32msvc-gcc -Wall -fPIC -I /usr/include/python2.7 -shared -o test.dll test.c
I get this error:
test.c:1: warning: -fPIC ignored for target (all code is position independent)
In file included from /usr/include/python2.7/Python.h:58,
from test.c:16:
/usr/include/python2.7/pyport.h:338:24: error: sys/select.h: No such file or directory
Am I doing something wrong?
You do this with it:
<your_compiler> <cython_generated_c_file> -o <your_outputfilename> -fPIE -lpython<python_version>
<cflags> <ldflags>
To get cflags:
python-config --cflags
For ldflags:
python-config --ldflags
