I have decided to delete the files I had and do it from scratch again. To start with I am running git clone gitlab@git.skewed.de:count0/graph-tool.git I am then executing autogen.sh. This returns the following: libtoolize: putting auxiliary files in `.'. libtoolize: linking file `./ltmain.sh' libtoolize: putting macros in AC_CONFIG_MACRO_DIR, `m4'. libtoolize: linking file `m4/libtool.m4' libtoolize: linking file `m4/ltoptions.m4' libtoolize: linking file `m4/ltsugar.m4' libtoolize: linking file `m4/ltversion.m4' libtoolize: linking file `m4/lt~obsolete.m4' libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am. configure.ac:22: installing './compile' configure.ac:18: installing './config.guess' configure.ac:18: installing './config.sub' configure.ac:20: installing './install-sh' configure.ac:20: installing './missing' src/graph/Makefile.am: installing './depcomp' src/graph_tool/Makefile.am:3: installing './py-compile' configure.ac:39: error: possibly undefined macro: PKG_INSTALLDIR If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. I can then run the configure file that it has generated but is this an error that I would need to fix first? If I run configure it seems to happily run to the end. The only on-screen message that sticks out at me as being odd is: ./configure: line 16350: PKG_INSTALLDIR: command not found If I read the config.log (attached config.log <http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/file/n4026818/config.log> ) though I find a number of error messages largely revolving around ac_nonexistent.h, such as: conftest.c:11:28: fatal error: ac_nonexistent.h: No such file or directory #include <ac_nonexistent.h> and: conftest.c:54:26: fatal error: minix/config.h: No such file or directory #include <minix/config.h> Does anybody know what I need to do about these? Any help would be greatly appreciated! Best wishes, Philipp -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...
