Trouble rebuilding Code::Blocks from trunk.

[ptDev]

I attempted a full clean rebuild (manually deleted all output binaries and even object files) of a recent Code::Blocks through the CodeBlocks.workspace file.

Using TDM-GCC 4.7.1 on Windows, with which I built wxWidgets 2.8.12.

Early on, I got a linker error when building the autorevision target, and I can't see where it comes from.

The compiler output:

The linker input warnings intrigue me as well.

[ptDev]

I think I found the problem. There is a generated command-line compiler command with a line break escape sequence in it for no good reason, when it should have been two separate commands.

Code

cmd /c if exist base\tinyxml\libtxml.a del base\tinyxml\libtxml.a\nar.exe -r -s base\tinyxml\libtxml.a .objs\base\tinyxml\tinystr.o .objs\base\tinyxml\tinyxml.o .objs\base\tinyxml\tinyxmlerror.o .objs\base\tinyxml\tinyxmlparser.o

Has anyone else reproduced this?

Alpha any ideas about this problem?

ptDev: What revision of CB are you using?

[ptDev]

Was a build of revision 8834.

Using 8855, I don't reproduce it any more.

It is strange, because there is no change in options_gcc.xml in between those revisions.

[Alpha]

The fix was in rev. 8846, however, what is strange is that the command

Code

cmd /c if exist base\tinyxml\libtxml.a del base\tinyxml\libtxml.a\nar.exe -r -s base\tinyxml\libtxml.a .objs\base\tinyxml\tinystr.o .objs\base\tinyxml\tinyxml.o .objs\base\tinyxml\tinyxmlerror.o .objs\base\tinyxml\tinyxmlparser.o

was added in 8847...  Did your files get mixed?

[MortenMacFly]

Has anyone else reproduced this?

Yes, me.
I removed the first line (the cmd.exe) thing in the advanced option, now it works again. I forgot to report though.

Mystery solved, then.

It is possible (though unlikely) that files got mixed, which would explain why the issue came and went.

I'm not sure.
Morten: Is trunk in working state or do we have to change something to make it working as expected?

For me its not. Even if I have a linefeed between the two commands it does not work. (BTW: There was a linefeed before.)

I can try a fresh re-compile though...

[ptDev]

Was there any change in how the compiler plugin interpretes the linefeed?

[Alpha]

I am not on Windows right now, but when I have access, I will explore this.  (Although it did work last time I checked...)

Was there any change in how the compiler plugin interpretes the linefeed?

No, the internal use has remained the same (the only change was a recent fix to correct loading from the XML files).
