I get the following if I try to compile the GtkAda minimal example of GNAT Programming Studio 6.1.0w:

gnatlink: error when calling /usr/bin/gcc-4.6
The command executed by GPS:
gnatmake -d -P/home/myuser/own projects/ada/AdaTest.gpr -vP2 -j4 -g
The same command works if I try it from a terminal and it also worked in GPS 5.0 (which executed the same command as the newest, 6.1.0w)
What can cause this and how can I make GPS work?
You asked the same question on comp.lang.ada I believe. Just for the record, the answer from Ludovic Brenta was to: install libpixman-1-dev, and then edit the Linker'Linker_Options switch in your project file so that it contains "-lpixman-1".
It is possible that when running from GPS, the linker sees a different version of one of the libraries that come with gtk+, and this would have a different list of dependencies.

Hello I am using given code from the examples to test if I have installed netcdf correctly. I installed the prebuilt netCDF4.8.1-NC4-DAP-64 and put it in the environment variable path (I checked to make sure it worked, it did. Next I did #include "netcdf.h" in the main c file and then made the make file as such:
CC = gcc
EXECUTABLES = try
INCLUDES = -IC:/Program\ Files/netCDF\ 4.8.1/include/
CFLAGS = $(INCLUDES)
LIBS = -LC:/Program\ Files/netCDF\ 4.8.1/lib -lnetcdf -lmfhdf -ljpeg -lhdf5_hl -lhdf5 -lz -lm
all: $(EXECUTABLES)
try: try.c
$(CC) $(CFLAGS) -o try try.c $(LIBS)
clean:
rm core $(EXECUTABLES) *.o
I tried to look at forums and added diffrent flags such as all of
-lnetcdf -lpnetcdf -lmfhdf -ldf -ljpeg -lhdf5_hl -lhdf5 -lz -lsz -lm
but it would throw
gcc -IC:/Program\ Files/netCDF\ 4.8.1/include/ -o try try.c -LC:/Program\ Files/netCDF\ 4.8.1/lib -lnetcdf -lpnetcdf -lmfhdf -ldf -ljpeg -lhdf5_hl -lhdf5 -lz -lsz -lm

Any help is appreciated, Thank You
Update!! I think that because the files I was trying to link were .lib, gcc was not linking it. I changed form vscode to vs community and added the .lib and it started to work properly.
Instead of compiling with gcc I compiled with MSVC.
I'm a beginner in the Database community. I have been trying to interface with MonetDB using C/C++ MAPI. I have installed MonetDB on my Ubuntu 14.04 LTS machine and when I try to compile a sample program from here, I get the following error:
$ gcc test.c -I /usr/include/monetdb -lmapi

This question has previously been asked here and the answer did not solve the problem (although the answer was accepted, I'm not sure why). Any help/directions would be great!
On Ubuntu 18.04 using:
pkg-config --libs monetdb-mapi and pkg-config --cflags monetdb-mapi
Won't work because Ubuntu doesn't have a bzip2.pc:
Here how it worked:
gcc main.c -I /usr/include/monetdb -lmapi -lssl -lcrypto -lstream -lcurl -llzma -lbz2
I tried to compile test application for MonetDB under Ubuntu 14.04 LTS Trusty Tahr. I followed the download instructions from official site, installation was successful, then I installed a bunch of other packages in order to copmpile it. Now when I try to compile and link test application I get the following errors:
libtool: compile: gcc -c -I/usr/include/monetdb test.c -fPIC -DPIC -o .libs/test.o
libtool: compile: gcc -c -I/usr/include/monetdb test.c -o test.o >/dev/null 2>&1

What I'm doing wrong? What should I additionally install or change in compilation options for successful linking of test example?
I was able to compile the example on Ubuntu 14.04 with MonetDB installed from the Ubuntu binary packages after installing the (additional) package libmonetdb-client-dev with the following command:
gcc test.c -I /usr/include/monetdb -lmapi
Did you compile and install MonetDB from source? In this case, which prefix was used?
Here how it worked using ubuntu 18.04
gcc main.c -I /usr/include/monetdb -lmapi -lssl -lcrypto -lstream -lcurl -llzma -lbz2
i experience the undefined reference to `dlopen' problems since I have upgraded to ubuntu 13.10 and gcc 4.8.1.
The makefiles are working for years already. the particular call is
gcc -rdynamic -o ov_dbutil ov_dbutil.o libov.so -ldl
The errors are:
libov.so: undefined reference to `dlopen'
libov.so: undefined reference to `dlclose'
libov.so: undefined reference to `dlerror'
libov.so: undefined reference to `dlsym'
collect2: error: ld returned 1 exit status
make: *** [ov_dbutil] Error 1
is it a gcc problem?
ov_dbutil is compiled with the following lines
gcc -g -Wall -O0 -shared -std=c99 -fno-strict-aliasing -DPLT_SYSTEM_LINUX=1 -DPLT_USE_BUFFERED_STREAMS=1 -DPLT_SERVER_TRUNC_ONLY=1 -DNDEBUG -DOV_SYSTEM_LINUX=1 -I../../../plt/include/ -I../../../ks/include/ -I../../include/ -I../../model/ -I../../source/codegen/ -I../../source/builder/ -I../../source/example/ -I../../source/kshist/ -I../../source/dynov/ -I../../source/tasklib/ -I../../source/dbparse/ -I../../source/dbdump/ -I../../../../libml/ -I../../include/runtimeserver/ -I. -c ../../source/dbutil/ov_dbutil.c -o ov_dbutil.o
no errors or warnings
Add -Wl,--no-as-needed as linker arguments.
My issue was solved by adding -ldl in the lining line of the .so you want to link agains, it was called libov.so in the upper example.
I've installed the following two msi on my Windows 7 (basic) 64-bit — I downloaded the msi from here.
gstreamer-sdk-devel-x86_64-2013.6.msi
gstreamer-sdk-x86_64-2013.6.msi
Now I'm trying to build this hello world program using MinGW (GCC 4.8.1) and the linker is giving me trouble, saying this:

Which lib(s) am I missing?
Here are options which I used to build the project (taken from my make output):

What is lacking in this?
What should I do in order to resolve this?
I suspect your are using MinGW's default GCC compiler which targets the x86 architecture but you have downloaded the x86_64 version of the SDK. The linker can find the libraries but I won't be able to use them.
We strongly recommend to use cerbero's build system to setup the development environment. It will take care of downloading a working toolchain and compile all the build dependencies (autotools, gettext, libtoo, pkg-config, etc...)
You will find detailed instructions here in the section Build a single project with the SDK
In short:
checkout cerbero's repo
run the bootstrap command with: ./cerbero-uninstalled -c config/win64.cbc bootstrap
enter the development shell with: ./cerbero-uninstalled -c config/win64.cbc shell
