| 3 | autogen.mk is a makefile provided to automatically update the GNU autotools |
| 4 | build system. It will run Bakefile, aclocal, and autoconf as appropriate. |
| 5 | |
| 6 | The .m4 files required for running aclocal are located in build/aclocal. |
| 7 | When upgrading software that wxWidgets depends on (for example, Bakefile, |
| 8 | cppunit, GTK, SDL, or others) it is advisable to upgrade the .m4 files |
| 9 | located in the build/aclocal directory. |
| 10 | |
| 11 | It is particularly important that if you use a newer version of Bakefile |
| 12 | to generate the Makefile.in files that you use the newer bakefile*.m4. |
| 13 | Because build/autogen.mk is a Makefile it will automatically rerun |
| 14 | aclocal and autoconf as necessary whenever any m4 in build/aclocal is |
| 15 | newer than the generated aclocal.m4. |
| 16 | |
| 17 | You can achieve this simply by copying the new bakefile*.m4 files from |
| 18 | PREFIX/share/aclocal/ into the build/aclocal/ directory and |
| 19 | rerunning make -f build/autogen.mk. Note that you should _not_ preserve |
| 20 | source file times (don't use cp -p) or else it's possible your .m4 files |
| 21 | will be older than the generated aclocal.m4). |
| 22 | Example: |
| 23 | cp /usr/share/aclocal/bakefile*.m4 build/aclocal/ |
| 24 | make -f build/autogen.mk |
| 25 | |
| 26 | Please don't forget to commit updated .m4 files as well as updated aclocal.m4, |
| 27 | configure, and Makefile.in files to wxWidgets. |
