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