POMAKE: problem with command line length

[mtx500]

Hi Pelle,
here is another small issue:

POMAKE has a problem when the size of the command line exceeds ~1000 chars.

The following makefile demonstrates this:

Code Select Expand

DEFS=\
   /DVeryLongDefine01=VeryLongSubstitutionText01 \
   /DVeryLongDefine02=VeryLongSubstitutionText02 \
   /DVeryLongDefine03=VeryLongSubstitutionText03 \
   /DVeryLongDefine04=VeryLongSubstitutionText04 \
   /DVeryLongDefine05=VeryLongSubstitutionText05 \
   /DVeryLongDefine06=VeryLongSubstitutionText06 \
   /DVeryLongDefine07=VeryLongSubstitutionText07 \
   /DVeryLongDefine08=VeryLongSubstitutionText08 \
   /DVeryLongDefine09=VeryLongSubstitutionText09 \
   /DVeryLongDefine10=VeryLongSubstitutionText10 \
   /DVeryLongDefine11=VeryLongSubstitutionText11 \
   /DVeryLongDefine12=VeryLongSubstitutionText12 \
   /DVeryLongDefine13=VeryLongSubstitutionText13 \
   /DVeryLongDefine14=VeryLongSubstitutionText14 \
   /DVeryLongDefine15=VeryLongSubstitutionText15 \
   /DVeryLongDefine16=VeryLongSubstitutionText16 \
   /DVeryLongDefine17=VeryLongSubstitutionText17 \
   /DVeryLongDefine18=VeryLongSubstitutionText18 \
   /DVeryLongDefine19=VeryLongSubstitutionText19 \
   /DVeryLongDefine20=VeryLongSubstitutionText20 \
   /DVeryLongDefine21=VeryLongSubstitutionText21 \
   /DVeryLongDefine22=VeryLongSubstitutionText22 \
   /DVeryLongDefine23=VeryLongSubstitutionText23 \
   /DVeryLongDefine24=VeryLongSubstitutionText24 \
   /DVeryLongDefine25=VeryLongSubstitutionText25

POMAKEBug1.obj: POMAKEBug1.c
   @pocc.exe /Fo$@ /MT /W2 /Ze /O2 $(DEFS) $!


POMAKEBug1.c should exist but its contents are irrelevant.
POMAKE returns:
fatal error #1061: Can't open input file '@C:\DOCUME~1\xxxxxx\LOCALS~1\Temp\MKDA.tmp'.
POMAKE: fatal error: 'pocc.exe', error 1.

Hello,

Yes, the limit used by POMAKE is 1000. If the command line is longer, I create an "argument file" and change the syntax to: cmd @argfile. This assumes that "cmd" (POCC in this case) can handle @filename, which it can't - but the compiler driver, CC, can. You could change this from POCC ... to CC /c ...

I can't find the limit at the moment, but I think this was done because of a limitation for command lines in some Win 9X version. If it was a bit longer, probably 1024, it was truncated. Probably not an issue on Win NT/2K/XP, and maybe not even on Win 98. I will have to investigate...
