3a5bb506 - cpupower: fix lib default installation path

Tue, 02 Jul 2024 07:56:25 +0000

cpupower: fix lib default installation pathInvocation the tool built with the default settings fails:$ cpupowercpupower: error while loading shared libraries: libcpupower.so.1: cannotopen shared object file: No such file or directoryThe issue is that Makefile puts the library to "/usr/lib64" dir for a 64bit machine. This is wrong. According to the "File hierarchy standardspecification:https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standardhttps://refspecs.linuxfoundation.org/FHS_3.0/fhs-3.0.pdf"/usr/lib" dirs are intended for alternative-format libraries(e.g., "/usr/lib32" for 32-bit libraries on a 64-bit machine (optional)).The utility is built for the current machine and doesn't handle'CROSS_COMPILE' and 'ARCH' env variables. It also doesn't change bitdepth. So the result is always the same - binary for x86_64architecture. Therefore the library should be put in the '/usr/lib'dir regardless of the build options.This is the case for all the distros that comply with the'File Hierarchy Standard 3.0" by Linux Foundation. Most of the distroscomply with it. For example, one can check this by examining the"/usr/lb64" dir on debian-based distros and find that it contains only"/usr/lib64/ld-linux-x86-64.so.2". And examine that "/usr/lib" containsboth 32 and 64 bit code:find /usr/lib -name "*.so*" -type f | xargs file | grep 32-bitfind /usr/lib -name "*.so*" -type f | xargs file | grep 64-bitFix the issue by changing library destination dir to "/usr/lib".Signed-off-by: Roman Storozhenko Signed-off-by: Shuah Khan List of files: /linux-6.15/tools/power/cpupower/Makefile

tools/power/cpupower: Add 64 bit library detectionThe kernel-tools-lib rpm is installing the library to /usr/lib64, and not/usr/lib as the cpupower Makefile is doing in the kernel tree. Thisresulted in a conflict between the two libraries. After looking at howother tools installed libraries, and looking at the perf code intools/perf it looks like installing to /usr/lib64 for 64-bit arches is thecorrect thing to do.Checks with 'ldd cpupower' on SLES, RHEL, Fedora, and Ubuntu result inthe correct binary AFAICT:[root@testsystem cpupower]# ldd cpupower | grep cpupower libcpupower.so.0 => /lib64/libcpupower.so.0 (0x00007f1dab447000)Commit ac5a181d065d ("cpupower: Add cpuidle parts into library") added anew cpupower library version.
