| 18:56.34 | linuxjacques | I'm trying to build the powerpc-e500v2-linux-gnuspe sample from the latest HEAD and it's failing on PPL with "configure: error: Cannot find GMP version 4.1.3 or higher." |
| 18:56.50 | linuxjacques | yet it already built GMP 5.0.1 |
| 19:28.45 | y_morin | linuxjacques: revert to using GMP 4.3.2. |
| 19:30.11 | linuxjacques | y_morin|away: yeah I tried that - same error |
| 19:30.39 | linuxjacques | now trying without GRAPHITE which removes need for PPL |
| 19:33.54 | linuxjacques | hmm, it looks like the PPL configure sub-executable (conftest built by configure to check GMP version) was segfaulting |
| 19:34.23 | linuxjacques | I have these in my messages log: conftest[2258] trap divide error ip:400518 sp:7fffe99b26d8 error:0 in conftest[400000+1000] |
| 20:03.43 | y_morin|away | linuxjacues: that's perfectly normal. In the process of testing stuff, ./configure generates some executables and runs them. If some do segfault, it can be expected behavior. It happens here as well. |
| 20:20.31 | linuxjacques | y_morin|away: yeah it _could_ be normal, or it could be the conftest which is supposed to return a value based on the version of GMP - hard to tell. Either way, I can't get PPL to pass its configure test. |
| 20:20.56 | linuxjacques | the toolchains built without GRAPHITE / PPL |
| 20:21.00 | linuxjacques | toolchain |
| 21:20.34 | y_morin|away | linuxjacques: What's your host? Gentoo with PAX? |
| 21:21.04 | linuxjacques | y_morin: this time it's Fedora14 X86_64 |
| 21:21.10 | linuxjacques | (I do use gentoo at home) |
| 21:21.41 | linuxjacques | could it be picking up the host (Fedora) GMP libs? |
| 21:21.52 | y_morin | Can you look at the config.log from PPL and see what it was trying to do at the time of breakage? |
| 21:22.04 | y_morin | linuxjacques: yes it can do tht as well. |
| 21:22.09 | y_morin | *that |
| 21:22.47 | linuxjacques | y_morin: yeah I can find it again - it was building a little conftest which just linked a GMP lib (IIRC) and ensured the version was >= 4.1.3 |
| 21:23.22 | linuxjacques | the Fedora GMP would have been built with gcc 4.5.1 - not sure if that has a different ABI than 4.6.0 (which crosstool-ng is building) |
| 21:23.34 | y_morin | Yes, I know. But in the config.log, you'll see exactly what was going on: the program, the compile command line. |
| 21:23.50 | y_morin | Then you could redo the same build, but with the -Wl,-verbose flag |
| 21:24.00 | y_morin | And then you'd see where it finds the library. |
| 21:24.17 | y_morin | To rule out it picking the system library instead of our own version. |
| 21:24.42 | linuxjacques | y_morin: Ok looking |
| 21:25.08 | linuxjacques | but how would I be sure the env was the same between what I do on command line and crosstool-ng build? |
| 21:25.23 | linuxjacques | sometimes there are lib paths etc. |
| 21:25.28 | y_morin | The env has nothing to do when running gcc and ld. |
| 21:25.36 | y_morin | All that matters is the arguments on the command line. |
| 21:26.17 | y_morin | You'll see something like: 'failed program was' just after the last failure (other program failures are OK). |
| 21:28.11 | linuxjacques | configure files aren't exactly ... readable - looks like this check starts on line 11163 of the PPL configure |
| 21:28.30 | y_morin | linuxjacques: no, I'm speaking about the config.log, not the ./configure... |
| 21:29.17 | y_morin | just search for the error message. |
| 21:29.52 | linuxjacques | y_morin: aah, OK |
| 21:31.35 | linuxjacques | I used the same build dir to build without PPL, so it looks like it wiped out the ppl build dir - let me re-config and try it again (should only take a couple of minutes) |
| 21:31.50 | y_morin | OK, no problem... |
| 21:33.22 | linuxjacques | it's building GMP now - then maybe one other package, then PPL |
| 21:33.36 | y_morin | GMP -> MPFR -> PPL |
| 21:33.37 | linuxjacques | yeah it's GMP, MPFR, PPL |
| 21:34.20 | linuxjacques | OK, it failed on PPL, and there's a fresh segfault in my messages log - looking for PPL config.log now |
| 21:36.43 | linuxjacques | I believe this is the relevant part of the PPL config.log: http://pastebin.com/fQqBS7aC |
| 21:37.46 | linuxjacques | this is interesting: GMP header (gmp.h) and library (ligmp.*) version mismatch: header gives 4.3.1; library gives 5.0.1. |
| 21:38.02 | linuxjacques | the Fedora version of GMP is 4.3.1 |
| 21:38.17 | linuxjacques | so it's finding the correct lib but wrong headers? |
| 21:38.23 | y_morin | And you configured 5.0.1 in crosstool-NG, right? |
| 21:38.45 | linuxjacques | y_morin: int this case, yes, though I have tried 4.3.2 as well |
| 21:39.14 | linuxjacques | maybe I should remove the Fedora gmp-devel package |
| 21:39.56 | y_morin | In fact, if you look at the conftest compile line (6 in the pastebin), you'll see it does not pass any -I flag. |
| 21:40.26 | y_morin | No, companion libraries are becoming mainstream in current distors, and we have to support that as well. |
| 21:40.35 | y_morin | *distros |
| 21:40.56 | linuxjacques | yeah I didn't feel right suggesting it :-) |
| 21:41.19 | y_morin | And because it does not pass any -I flag, it includes gmpxx.h from your host include path, not our. |
| 21:41.34 | y_morin | (line 98 in the pastebin) |
| 22:01.09 | linuxjacques | y_morin: as a test, I removed the Fedora gmp-devel package, and now the PPL build fails with: conftest.cpp:84:19: fatal error: gmpxx.h: No such file or directory |
| 22:01.22 | linuxjacques | which I guess would be expected with no -I |
| 22:27.12 | linuxjacques | re-installing the Fedora gmp-devel package and choosing GMP 4.3.1 in crosstool-ng allows PPl to build |
| 22:38.05 | bhundven | y_morin: have you tested building x86_64 on i[x]86 with static toolchain? |
| 22:39.30 | y_morin | bhundven: probably not, I can't remember. I mostly do real crosses here (eg. ARM and MIPS). |
| 22:39.38 | bhundven | ok |
| 22:40.19 | y_morin | So if you tell me it is broken, I wouldn't be too surpised. Disapointed, maybe; surprised, no. :-/ |
| 22:40.26 | bhundven | heh |
| 22:40.57 | bhundven | well, I'm still trying to figure out the actual problem, so I'm not raising any alarms yet.. |
| 22:41.26 | y_morin | bhundven: but if you have a fix, tonight is your last chance at it before the release: I am rebuilding all samples before the release on Saturday evening. |
| 22:41.39 | bhundven | not yet... just getting into it. |
| 22:41.48 | bhundven | next release ;) |
| 22:42.10 | y_morin | And building all of them takes roughly 16h on my machine, so I'm not ready to handle a third or second build... |
| 22:42.16 | y_morin | Yep, probably! ;-) |
| 22:43.52 | y_morin | hates Java: the Java frontend takes 20min to build... |
| 22:44.43 | y_morin | linuxjacques: I'm not too sure what to expect at this step (I mean no -I). It works for me here. |
| 22:45.19 | y_morin | linuxjacques: I guess that, although you removed the -devel package, you still have the runtime (eg. the libgmp.so.x.y.z is still here) |
| 22:45.51 | y_morin | In this case, it can still link with it. It's just the headers it does not find... :-( |
| 22:45.57 | y_morin | Which is weird. |
| 22:46.00 | linuxjacques | y_morin: yeah removing the runtime would probably want to remove the compiler |
| 22:46.10 | y_morin | definitely, yes. Sad... |
| 22:46.32 | y_morin | OTOH, I am working on making the complibs in crosstool-NG optional, in case the host system already have them. |
| 22:47.03 | y_morin | But that's not ready, my host still does not have them (I'm still on Debian Lenny, and not ready to upgrade). |
| 22:47.21 | linuxjacques | lol, doing "yum erase gmp" wants to remove just about every package on the system |
| 22:47.31 | y_morin | He... |
| 22:48.31 | linuxjacques | Fedora rawhide has 4.3.2, maybe I'll build / install that |
| 22:53.26 | y_morin | linuxjacques: probably, yes. It is built with the host compiler, so it should be the ABI. |
