Description Mark Kettenis 2008-01-25 06:41:29 UTC

configure fails on OpenBSD with the following message:

checking for OPENSSL... Package openssl was not found in the pkg-config search path
configure: error: Package requirements (openssl) were not met:



Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables OPENSSL_CFLAGS
and OPENSSL_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.


This is a bit silly because OpenSSL is part of the OpenBSD base system.  Furthermore, setting OPENSSL_CFLAGS and OPENSSL_LIBS (to empty strings) doesn't
help.

Is there any reason not to just use AC_CHECK_LIB(crypto, SHA1_Init) or something
similar and fall back on pkg-config if that fails?

Comment 1 Alan Coopersmith 2008-04-24 19:06:59 UTC

Changed it to use PKG_CHECK_EXISTS to see if openssl.pc exists first,
and if not, to just link with -lcrypto.

Fixed in master in git commit b1ae7c79db78cc3b789701f81328669f9f8ed80f
and in server-1.5-branch with 7c05b4c6214a9bbc8968c49a40363f8461f527d5

The problem with that is that if openssl isn't installed, then there's
no error message at configure-time like there should be.

I just changed it to use AC_CHECK_LIB before PKG_CHECK_MODULES, (as suggested
in the original report), rather than using PKG_CHECK_EXISTS.

This fixes the missing error message for a system with no openssl. Hopefully
it doesn't also break anything.
