Hi,
I am trying to compile the project libgd
(https://github.com/libgd/libgd) with the option ENABLE_JPEG enabled.
I.e. first I downloaded the source code of libjpeg-turbo from
https://sourceforge.net/projects/libjpeg-turbo/files/2.0.0/, compiled it
and afterwards I started to compile libgd with this command:
cmake -G "Unix Makefiles" \
-DENABLE_JPEG=ON \
-DJPEG_INCLUDE_DIR="../${JPEG_DIR}" \
-DJPEG_LIBRARY="../${JPEG_DIR}/libjpeg.a" \
.
You can check the CMakeLists.txt in that project
(https://github.com/libgd/libgd/blob/master/CMakeLists.txt)
As you can see, I want to compile libgd with a static libjpeg library.
But I get several errors like this one:
/usr/bin/ld: .../libjpeg-turbo-2.0.0/libjpeg.a(jcmainct.c.o):
relocation R_X86_64_32S against `.text' can not be used when making a
shared object; recompile with -fPIC
When I use the shared library version of libjpeg, i.e. I try to compile
libgd with the shared version of libjpeg, i.e.
cmake -G "Unix Makefiles" \
-DENABLE_JPEG=ON \
-DJPEG_INCLUDE_DIR="../${JPEG_DIR}" \
-DJPEG_LIBRARY="../${JPEG_DIR}/libjpeg.so" \
.
then there is no error.
Is this a problem of CMake or a problem of the CMakeLists.txt of the
libgd project?
