I get the following error: Applying fixes ... + sed -f frysk/expr/antlr.tmp/CExprEvaluator.sed frysk/expr/antlr.tmp/CExprEvaluator.gen sed: file frysk/expr/antlr.tmp/CExprEvaluator.sed line 48: unterminated `s' command make[1]: *** [frysk/expr/Completer.antlered] Error 1 make[1]: Leaving directory `/notnfs/swagiaal/frysks/frysk.patches/frysk-core' make: *** [all-recursive] Error 1 If i type make it goes away, but make -j3 consistently fails
The problem seems to be with two .g.antlered implicit rules being run in parallel, which step on each other's .antlr-fixes temporary files. In this particular case, this is caused by missing rule: frysk/expr/CExprEvaluator.antlered: frysk/expr/Completer.antlered Makefile rules are generated from importVocab directives in .g files by way of Makefile.gen.sh, so frysk really tries to give make proper parallelization hints. So the real problem is with temporary file handling. I believe what happens is that antlr-warnings.awk produces e.g. CExprEvaluator.antlr-fixes, when suddently the other make invocation removes it via 'rm -f $$d/*.antlr-fixes'. So the file being just built is removed, and misses its beginning. Later on, there's 'for fix in $$d/*.antlr-fixes', which picks both files, the "healthy" one as well as the truncated one, and tries to use them as a sed source. For that reason both parallel make branches fail.

(javah-built): Delete. (ANTLR): Define. * Makefile.gen.sh: Rename .antlered to .antlred. Include *TokenTypes.txt in list of generated files. frysk-core/ChangeLog 2007-11-14 Andrew Cagney <cagney@redhat.com> * Makefile.am (ANTLR): Delete.
