I'm trying desperately to get the cuda toolkit running on my debian system, having cuda 11.7 and the nvidia drivers 515 installed via the .run file.
Unfortunately, I always get false when checking for cudart and curand libraries with my autoconf script. Skipping the checks, results in a missing cuda.h error while compiling (c++).
Runing nvcc --version:

In my ~/.bashrc i added:

I also tried to add /usr/local/cuda-11.7/lib64 to ld.so.conf. Runing sudo ldconfig -v | grep cuda gives:

Compilation works fine, when cuda was installed with apt, but I need a newer version than available in apt.
I would be glad, if someone could give me a hint about this. I am relatively new to the Linux world and therefore have problems to fix things myself.
As Fareanor explained, part of the solution was to add cuda to LIBRARY_PATH.
I also had to add cuda to CPATH.
Now it works and .bashrc contains:
export PATH=${PATH}:/usr/local/cuda-11.7/bin
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/cuda-11.7/lib64
export LIBRARY_PATH=${LIBRARY_PATH}:/usr/local/cuda-11.7/lib64
export CPATH=$CPATH:/usr/local/cuda/include
I try to make mathgl work, but the linker can't find the library. I installed it through the user repository from arch linux.
I just copied the example program:
#include <mgl2/mgl.h>
int main()
{
mglGraph gr;
gr.FPlot("sin(pi*x)");
gr.WriteFrame("test.png");
}
The official website states you need to link lmgl, but I get this error:
$ g++ main.cpp -lmgl
/usr/bin/ld: cannot find -lmgl
collect2: error: ld returned 1 exit status
I couldn't figure out where to start looking for the library. How can I see where it was installed?
I was looking for libmgl with ldconfig -p getting these results:
$ ldconfig -p | grep libmgl

libmgl2-qt5.so (libc6,x86-64) => /usr/lib/libmgl2-qt5.so
libmgl2-qt.so.7.5.0 (libc6,x86-64) => /usr/lib/libmgl2-qt.so.7.5.0

libmgl2-glut.so (libc6,x86-64) => /usr/lib/libmgl2-glut.so
As Amadeus indicated, using
$ g++ main.cpp -lmgl2
should work.
Some C++ project use TIFF library and OpenCV library at the same time.
The following warning is produced:
/usr/bin/ld: warning: libtiff.so.4, needed by /home/user/libs/opencv/lib/libopencv_highgui.so, may conflict with libtiff.so.5,
How can it be resolved?
If it matters I'm using Ubuntu and Eclipse.
/sbin/ldconfig -p > libs.txt show me

libopencv_highgui.so (libc6,x86-64) => /usr/lib/libopencv_highgui.so
But I don't know what it means, different versions of library?
I suggest you try the following:
find a newer version of libopencv_highgui.so compiled with libtiff.so.5
recompile libopencv_highgui.so with libtiff.so.5
delete libtiff.so.4 and make a symlink to libtiff.so.5 if you get a linker error
I am attempting to compile a test opengl program on ubuntu. I have installed bumblebee, the nvidia 304 driver and libgl1-mesa-dev, using apt-get.
I can see the file /usr/lib/libGL.so.1 - and yet compiling with g++ and the flag -lGL returns the error: error: cannot find -lGL.
Any ideas on what I can do to fix this?

Hello I'm a newbie in compiling shared libraries.
My shared library depends on curl, ssl and crypto.
I've compiled the libcurl and the output libraries are:
libcurl.so.4 --> libcurl.so.4.3.0
libcurl.so.4.3.0
and I've compiled my shared library using the following command:
g++ -m32 -shared \
-o libtestshared.so.1 \
-fPIC ../build/*.o \
-lpthread \
../openssl/lib/libssl.so.1.0.0 \
../openssl/lib/libcrypto.so.1.0.0 \
../curl/lib/libcurl.so.4.3.0
But when I figure out what are the libraries my library depends on, I found:
ldd libtestshared.so.1
linux-gate.so.1 => (0x00e2a000)
libpthread.so.0 => /lib/libpthread.so.0 (0x00aec000)
libssl.so.1.0.0 => /home/usr1/openssl/lib/libssl.so.1.0.0 (0x0034c000)
libcrypto.so.1.0.0 => /home/usr1/openssl/lib/libcrypto.so.1.0.0 (0x003a8000)
libcurl.so.4 => /home/usr1/curl/lib/libcurl.so.4 (0x001cf000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00229000)
libm.so.6 => /lib/libm.so.6 (0x006be000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00eaf000)
libc.so.6 => /lib/libc.so.6 (0x006e8000)
/lib/ld-linux.so.2 (0x0055e000)
libdl.so.2 => /lib/libdl.so.2 (0x001ba000)
librt.so.1 => /lib/librt.so.1 (0x00314000)
Why only libcurl is refereing to the symbolic link?
