3 | Subject: [PATCH] cmcurl: link librt |
||
4 | |||
5 | When cmake is linked against LibreSSL, there might be an indirect |
||
6 | dependency on librt on certain systems if LibreSSL's libcrypto uses |
||
7 | clock_gettime() from librt: |
||
8 | |||
9 | [ 28%] Linking C executable LIBCURL |
||
10 | .../lib/libcrypto.a(getentropy_linux.o): In function `getentropy_fallback': |
||
11 | getentropy_linux.c:(.text+0x16d): undefined reference to `clock_gettime' |
||
12 | getentropy_linux.c:(.text+0x412): undefined reference to `clock_gettime' |
||
13 | collect2: error: ld returned 1 exit status |
||
14 | make[5]: *** [Utilities/cmcurl/LIBCURL] Error 1 |
||
15 | |||
16 | Modify the cmcurl CMakeLists.txt to check for clock_gettime() in librt |
||
17 | and unconditionally link the rt library when the symbol is found. |
