| Attachments: | Crash of makedepend with options shown | ||
makedepend crashed when being executed in src/mapi/shared-glapi/. If your xutils-dev is not up-to-date, update it first. If it does not help, could you run makedepend manually and maybe change some of its options to see if the crash can be avoided? You can see how mesa executes makedepend by removing the last "@" sign in src/mapi/shared-glapi/Makefile. (In reply to comment #1) > makedepend crashed when being executed in src/mapi/shared-glapi/. OK > If your xutils-dev is not up-to-date, update it first. Thanks for mentioning this. I use Debian "unstable" which has the latest packages available; I update frequently. As it turns out, libc6 and xutils-dev had just been updated. My first assumption was that the bug was in one of those updates and not in the Mesa sources. After downgrading to the previous version of xutils-dev (7.5+5) and two previous Debian releases of libc6 (all versions were 2.11.2, but the Debian maintainers often add patches and release new builds) I found that in all combinations of xutils-dev + libc6 that I tried the crashing of makedepend only appeared with commit 9767d3b5... (and after), but all prior commits that I tried during the bisect process worked fine. This information was known to me when I posted the bug report, but I failed to mention it because I wrongly assumed it was irrelevant. The current version of xutils-dev in Debian unstable is 7.6+1. > If it does not help, could you run makedepend manually and maybe change some > of its options to see if the crash can be avoided?

Is there something wrong with that combination of options? (My current build setup has been working for nearly a month, so I'm assuming it's OK to use.)

but it was non-fatal and compilation just carried on. since it's non-fatal who knows how long it were happening.
glibc is 2.12.2, makedepend is 1.0.3.

Now I need to do surgery on my homemade 'debian' directory to get the packages building again, but that should not take long. As a non-developer, may I ask a couple of questions: 1. Are you losing necessary dependency info by simply filtering out the indirect header file specified by MAPI_ABI_HEADER? 2. Has Mesa been building correctly for you between 9767d3b... and b825e49...? I presume so, and I wonder whether you build with way different configure options or whether you have some different build tools (or versions of build tools). Thanks, Dave W.

I built normally. I think makedepend was also crashing for me, but the error was silently redirected to /dev/null and I luckily had a syntactically correct "depend" file. > > Thanks, > Dave W.

Not "luckily," though, since it prevented you from catching the problem before you applied the commit that caused makedepend to barf. In the end, I'm glad I could help you to find the problem. DW |

I have been testing r600g lately, having seen all of the excitement on Phoronix about how well it is performing. As a Debian user, I cannot get r600g builds of Mesa from the Debian repos so I have been forced to build my own DEBs to be able to use r600g at all. Since I am not a developer, it is possible that I have goofed up the build process. However, I have been using my current build procedure without problems for nearly a month... until today. Retrieving the latest 7.11-devel version of Mesa using git, I found that /usr/bin/makedepend was failing with a backtrace early in the build. Bisecting, I found that commits up to and including 97185bf2654f7e72d8bfcc216f905492655d4c77 still worked fine. The next commit, 9767d3b5ad08640737e9d8dd4feb046478ae1f4b was broken.

This is only because I stuck very closely to the Debian build setup to get my DEB packages, and they build many more packages than I do. If this turns out to be a real bug, instead of some error on my part, then I guess it was for the best that I was building more than I need to and discovered the problem. HTH. If more info would be helpful, just let me know.
