#32415: flex configure fails when an existing broken flex is installed ---------------------------------+------------------------------------------ Reporter: mparchet@… | Owner: mww@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.0.3 Keywords: | Port: flex ---------------------------------+------------------------------------------ Comment(by ryandesign@…): Thanks. That config.log doesn't seem to have been created by a MacPorts- initiated installation attempt. I see on line 7 that it was created by just running "./configure"; MacPorts would have run "./configure --prefix=/opt/local --infodir=/opt/local/share/info --mandir=/opt/local/share/man". Perhaps after the MacPorts build failed, you tried running ./configure again manually? Further down, on line 39, it shows the parts of your PATH. Since this config.log was not made in the context of MacPorts, it shows your shell environment's PATH, not the PATH MacPorts would set. It shows you have the MacPorts paths /opt/local/bin and /opt/local/sbin in your PATH four times each, which is not a problem but is redundant. It also shows you have /sw/bin and /sw/sbin in your PATH, which is a problem if those directories contain anything. Those directories are part of Fink (another package manager) and it's not supported to have more than one package manager installed at a time; doing this can lead to conflicts and unexpected behavior. Please decide whether you would like to use Fink or MacPorts (or Homebrew, even), and uninstall the other(s). It also shows that your PATH contains /usr/local/bin. This is part of the default PATH on OS X, and it's not a problem if there's nothing in there. But /usr/local could contain software you installed manually, or using Homebrew; either would again be a problem for MacPorts and a potential source of conflicts and problems. Ports built using MacPorts might look in /usr/local for headers or libraries and find them and use them. And this is exactly what happened in your case, according to the log. On line 334 it says: {{{ configure:4877: checking lex output file root configure:4888: flex conftest.l dyld: Library not loaded: /usr/local/lib/libintl.3.dylib Referenced from: /opt/local/bin/flex Reason: image not found ./configure: line 4889: 1002 Trace/BPT trap: 5 flex conftest.l }}} This shows that you already have flex installed with MacPorts, and that at the time it was installed, it found a copy of the gettext internationalization library, libintl, in /usr/local/lib, and used it instead of the MacPorts version it was supposed to use. Since then, perhaps at our direction, you removed that libintl from /usr/local/lib, so now MacPorts flex can't find it and so it can't run. The solution is to deactivate this broken flex, then clean the flex port and try to build it again. {{{ sudo port -f deactivate flex sudo port clean flex sudo port install flex }}} It is possible you have other programs or libraries installed by MacPorts that are also inadvertently linked with libraries in /usr/local/lib (or /sw/lib). You could use `otool -L` to examine all of your programs and libraries, and if you find any, ensure those non-MacPorts libraries are gone, then rebuild the affected port(s). For example to rebuild port ''foo'' you could: {{{ sudo port -n upgrade --force foo }}} -- Ticket URL: <https://trac.macports.org/ticket/32415#comment:5> MacPorts <http://www.macports.org/> Ports system for Mac OS
