Attaching the complete > /root/install/squid-3.5.26/src/adaptation/ecap/Host.cc:41: undefined > reference to `libecap::headerTransferEncoding' It looks like Squid found eCAP header files but did not find libecap. Posting ./configure output and the failed linker command (should be right above the first "undefined reference" error) may help triage this further. Linking to a complete build log (starting with ./configure) may reduce the number of follow up questions. Also, what does /usr/local/lib/pkgconfig/libecap.pc contain?
