| markAppelit | I was trying to build the ios viewer from the git sources but found that there seems to be an issue with the make command in build_libs.sh (on my mac mini)... because the build_libs.sh specifies -j4 make seems to hang (probably because of some implicit dependencies). As soon as I remove the -j4 it compiles normally but takes way longer then it should... | 12:01.12 |
| kens | markAppelit : which product are you referring to ? | 12:01.44 |
| markAppelit | this one http://git.ghostscript.com/?p=mupdf-ios-viewer.git;a=summary | 12:02.06 |
| | using tagged version #1.11 | 12:02.27 |
| Robin_Watts | -j4 says "build with up to 4 jobs in parallel". | 12:02.30 |
| kens | OK so that's MuPDF, while the MuPDF developers do listen here,you might get more response over on #mupdf | 12:02.35 |
| kens | shuts up since Robin is here | 12:02.45 |
| Robin_Watts | I'd simply bet that at -j4 is running your mac mini out of memory, or making it swap like mad. | 12:02.59 |
| markAppelit | I know I did my fair share of C/C++ programming | 12:03.07 |
| Robin_Watts | So remove the -j4 and live with it taking longer. | 12:03.24 |
| kens | Try -j2 maybe ? | 12:03.41 |
| markAppelit | I did run -j2 also (and no it is not swapping and/or running out of memory (3G free)) it does look like a missing Makefile dependency breaking parallel builds | 12:04.23 |
| | and since the build_libs.sh is in the repo I thought I should mention it | 12:04.38 |
| | it hangs on/after running ranlib for the third party libs | 12:05.06 |
| | (maybe/probably because the "$(OUT)/%.a :" rule does not specify the objects it requires to actually run) | 12:05.51 |
| | I mean specify explicitly instead of implicit in the AR_CMD | 12:06.44 |
| Robin_Watts | tor8 is the expert here. | 12:08.42 |
| tor8 | no idea. parallell builds work on all other platforms. is apple's 'make' tool different/buggy? | 12:09.47 |
| markAppelit | it is apple so what do you think ;) | 12:10.07 |
| tor8 | markAppelit: the -j4 is not required, but something we do out of habit to speed up build times | 12:11.34 |
| | if it's causing trouble with Xcode then we can easily remove it. | 12:11.53 |
| | the makefile dependencies *should* be solid, we've gone to a lot of effort to make sure of it. that said, it's a notoriously difficult thing to get right. | 12:12.20 |
| markAppelit | I know I did already remove it but like I said I thought I should mention it... | 12:12.26 |
| tor8 | markAppelit: we appreciate it... biggest problem is none of the developers use macs regularly anymore. | 12:12.55 |
| | so these things tend to go un-noticed | 12:13.04 |
| markAppelit | me neither, I was checking it out for a project... normally run linux and am quite happy with it :) | 12:14.06 |
| navi_se_ | @llpp boss, if here, is there a way to send the document to print and select a page range? | 14:29.18 |
| | I know you can send to printer with Ctrl+P (which is undocumented in the LLPP help page, I believe) | 14:29.47 |
| sebras | navi_se_: you are looking for malc_ (llpp maintainer), and he's neither here, nor in the #mupdf channel at the moment. | 15:22.56 |
| navi_se_ | sebras: thanks, I didn't remember his name | 16:01.18 |
