#45258: CSSC @1.4.0 does not build: #error "Please include config.h first." --------------------------+-------------------------- Reporter: ryandesign@… | Owner: ryandesign@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.1 Keywords: snowleopard | Port: CSSC --------------------------+-------------------------- René J.V. Bertin reported on the mailing list that CSSC @1.4.0 does not build on Snow Leopard: {{{ :info:build In file included from /usr/include/c++/4.2.1/i686-apple- darwin10/x86_64/bits/os_defines.h:61, :info:build from /usr/include/c++/4.2.1/i686-apple- darwin10/x86_64/bits/c++config.h:41, :info:build from /usr/include/c++/4.2.1/cstdio:50, :info:build from bodyio.h:26, :info:build from bodyio.cc:26: :info:build ../gl/lib/unistd.h:135:3: error: #error "Please include config.h first." }}} I am able to reproduce this issue on Snow Leopard with gcc 4.2.1, but it builds fine on later versions of OS X with clang. The problem may be specific to older versions of GCC. It was also [http://lists.gnu.org/archive/html/bug-cssc/2014-08/msg00003.html reported to the developers] by someone using GCC 4.4.7 on Linux. I am not able to reproduce it with GCC 4.8.3 on OS X 10.10 beta. The problem seems to be that the project provides a wrapper around the system header unistd.h, which requires that the project-specific file config.h first be included, but this is not being done in every instance. The developers [http://lists.gnu.org/archive/html/bug- cssc/2014-09/msg00003.html provided] [http://git.savannah.gnu.org/cgit/cssc.git/commit/?id=9737f41b5d2a49e61061e9f... a patch]. The patch did not apply cleanly to the 1.4.0 sources (in the portion targeting the file file.cc). After fixing that, the build still failed with a similar error, this time in version.cc. version.cc does not include unistd.h, but it includes another system header, stdio.h. Perhaps stdio.h or one of the files it eventually includes includes unistd.h. -- Ticket URL: <https://trac.macports.org/ticket/45258> MacPorts <http://www.macports.org/> Ports system for OS X
