I've been trying to build squid 3.2.0.14 on CentOS with eCAP enabled. I've built and installed libecap, and verified that the libraries are installed, but I get this error when configuring squid: <snip> checking for EXT_LIBECAP... no configure: error: Package requirements (libecap > 0.2 libecap < 0.3) were not met: No package 'libecap' found No package 'libecap' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables EXT_LIBECAP_CFLAGS and EXT_LIBECAP_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. </snip> I've actually put the libraries in both /usr/lib and /usr/local/lib, to no avail. I've also tried 3.2.0.12 and I get the same error. Any thoughts as to why I get this? Thanks, Matt
