Trouble rebuilding Code::Blocks from trunk.

(1/3) > >>

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.

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
