Top Forums Programming How to make use others' C library installed not for the system-wide (Ubuntu/Linux)? Post 303043007 by GRMartin on Wednesday 15th of January 2020 06:17:24 PM

If you link to a shared library intead of the archive it's a little more complicted. If the shared library isn't installed in a directory know to the loader then you need to tell it where to find it. The rpath option I mentioned is passed to the linker and added to the executable. As long as the shared library is in the same place it will find it. You can also set LD_LIBRARY_PATH to the directory where it is. One way to do this (in a bash shell) is:
Code:
export LD_LIBRARY_PATH=/home/yifangt/Study/C/VCF/htslib-1.10.2; ./vcf_parser01

NAME
install_name_tool - change dynamic shared library install names SYNOPSIS
install_name_tool [-change old new ] ... [-rpath old new ] ... [-add_rpath new ] ... [-delete_rpath new ] ... [-id name] file DESCRIPTION
Install_name_tool changes the dynamic shared library install names and or adds, changes or deletes the rpaths recorded in a Mach-O binary. For this tool to work when the install names or rpaths are larger the binary should be built with the ld(1) -headerpad_max_install_names option. -change old new Changes the dependent shared library install name old to new in the specified Mach-O binary. More than one of these options can be specified. If the Mach-O binary does not contain the old install name in a specified -change option the option is ignored. -id name Changes the shared library identification name of a dynamic shared library to name. If the Mach-O binary is not a dynamic shared library and the -id option is specified it is ignored. -rpath old new Changes the rpath path name old to new in the specified Mach-O binary. More than one of these options can be specified. If the Mach-O binary does not contain the old rpath path name in a specified -rpath it is an error. -add_rpath new Adds the rpath path name new in the specified Mach-O binary. More than one of these options can be specified. If the Mach-O binary already contains the new rpath path name specified in -add_rpath it is an error. -delete_rpath old deletes the rpath path name old in the specified Mach-O binary. More than one of these options can be specified. If the Mach-O binary does not contains the old rpath path name specified in -delete_rpath it is an error. SEE ALSO
