Top Forums Programming How to make use others' C library installed not for the system-wide (Ubuntu/Linux)? Post 303043006 by yifangt on Wednesday 15th of January 2020 05:28:11 PM

Come to ld_config now

The compiling worked after:
Code:
$ LIBROOT="/home/yifangt/Study/C/VCF/htslib-1.10.2"
$ gcc -Wall -O3 -o vcf_parser01 vcf_parser01.c vcf.c  -I ${LIBROOT}/htslib -I ${LIBROOT} -L ${LIBROOT}  -lhts
$ ./vcf_parser01: error while loading shared libraries: libhts.so.3: cannot open shared object file: No such file or directory
$ ldd ./vcf_parser01
    linux-vdso.so.1 (0x00007ffdde13d000)
    libhts.so.3 => not found
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fa2c16bd000)
    /lib64/ld-linux-x86-64.so.2 (0x00007fa2c1cb0000)

It seems I'm getting closer to the point now. The shared library libhts.so.3 is located in ${LIBROOT}.
I did not mean to be lazy without digging the ld_config(?) or related subjects, but simply to stay consistent with this same example to avoid confusion.
How to ensure the dynamic library is available for the new executable vcf_parser01 just compiled?

Thanks!
