| Subject: Build: Use AM_SILENT_RULES if requested |
| |
| So now you can run "./configure --enable-silent-rules && make" to get |
| output like this: |
| |
| | CC liblzma_la-common.lo |
| | CC liblzma_la-block_util.lo |
| | CC liblzma_la-easy_preset.lo |
| [...] |
| |
| This makes it easier to see what file each batch of compiler warnings |
| is associated to. Since on the other hand it makes errors harder to |
| reproduce by hand (you have to use "make V=1"), disable it by default. |
| |
| The implementation uses m4_ifdef to avoid depending on an automake |
| version that implements AM_SILENT_RULES (1.11 or greater). |
