| 4 | Subject: [PATCH] ldso: Use syslibdir and libdir as default pathes to libdirs |
| 5 | |
| 6 | In absence of /etc/ld-musl-$(ARCH).path ldso uses default path to search |
| 7 | libraries /lib:/usr/local/lib:/usr/lib. |
| 8 | |
| 9 | However this path isn't relevant in case when library is put in dirs |
| 10 | like lib64 or libx32. |
| 11 | |
| 12 | Adjust CFLAGS_ALL to pass syslibdir as SYSLIBDIR and libdir as LIBDIR |
| 13 | preprocessor macroses to construct default ldso library search path |
| 14 | in ldso/dynlink.c::SYS_PATH_DFLT. |
| 15 | |
| 16 | Upstream-Status: Pending |
