Issue with zlib for compliing code?

[bch-bda]

I'm having an issue with the installation of the package (v 0.5.6) on my Linux system (distribution is centos 6.7; gcc version 5.3.0). When compiling the source code I get the following error when running the 'make' command:

LINKER:/gfs/apps/apps/gcc-5.3.0/bin/g++ -O3 -Wall -Wextra -std=c++14 -lstdc++
LD_FLAGS:-lgsl -lgslcblas -lm -lz

collect2: error: ld returned 1 exit status
bin.stu:17:5: command for bin/ssimp failed with exit status 1
make: *** [bin/ssimp] Error 1

Is this an issue with zlib? I'm currently using version 1.2.3 (July 18th 2005).

Thanks,
Ben

Is this still an open issue for you, @bch-bda ?

I see that the version of gcc that you use is from 2014. And you say that your zlib version is from 2005. So maybe it'll be difficult to get it working with old versions like that

Today, I had a similar - but slightly different - problem that arose while attemping to compile src/libStatGen/libStatGen.a. I resolved it by rebuilding libstatgen:

# Starting in the ssimp directory, change to this subdirectory
cd src/libStatGen
# Then clean it
make clean
# Go back to the top-level ssimp directory
cd ../..
# try again to rebuild everything. This will start by rebuliding libStatGen
make

I don't think it will work, but maybe it will!
