- autogen.mk
- autogen.mk is a makefile provided to automatically update the GNU autotools
- build system. It will run Bakefile, aclocal, and autoconf as appropriate.
- The .m4 files required for running aclocal are located in build/aclocal.
- When upgrading software that wxWidgets depends on (for example, Bakefile,
- cppunit, GTK, SDL, or others) it is advisable to upgrade the .m4 files
- located in the build/aclocal directory.
- It is particularly important that if you use a newer version of Bakefile
- to generate the Makefile.in files that you use the newer bakefile*.m4.
- Because build/autogen.mk is a Makefile it will automatically rerun
- aclocal and autoconf as necessary whenever any m4 in build/aclocal is
- newer than the generated aclocal.m4.
- You can achieve this simply by copying the new bakefile*.m4 files from
- PREFIX/share/aclocal/ into the build/aclocal/ directory and
- rerunning make -f build/autogen.mk. Note that you should _not_ preserve
- source file times (don't use cp -p) or else it's possible your .m4 files
- will be older than the generated aclocal.m4).
- Example:
- cp /usr/share/aclocal/bakefile*.m4 build/aclocal/
- make -f build/autogen.mk
- Please don't forget to commit updated .m4 files as well as updated aclocal.m4,
- configure, and Makefile.in files to wxWidgets.
