Dear all, I am very, very new to this list and very new to autoconf and friends. In addition I don't know much about linux, so here is my question: For my actual project I use a third-party-header-file. The user should get it from the web and put it do /usr/include or /usr/local/include. With autoconf I would like to check the presence of the header-file, but AC_CHECK_HEADER fails. The header-file to be checked is in /usr/include AND /usr/local/include. What do I miss? AC_CHECK_FILE works for this file, so my additional question is, what advantage brings _HEADER in my case? I am pretty sure that somewhere out there my question was already answered, but I dint find it so far. Thanks in advance for any hint or link!!!!
