Source: milter-greylist Version: 4.6.4-4 Tags: patch upstream User: debian-cr...@lists.debian.org Usertags: ftcbfs
milter-greylist fails to cross build from source, because it uses AC_RUN_IFELSE in multiple occasions. In this bug report, I'm considering only the first two of them. There, we want to check whether linking -lcurl requires -lcrypto. In this case, running the program does not yield any added value. We are using no symbols from either library and if running fails, linking should fail already. Thus, I am proposing to change AC_RUN_IFELSE to AC_LINK_IFELSE here. I'm attaching a patch for your convenience. Note that this patch does not make milter-greylist cross buildable. That's ok. Please close this bug anyway when doing something about the -lcurl test.
