Description Stefan Bruda 2004-11-07 11:33:57 UTC

Yet aanother MOL build problem, this one probably unrelated to the kernel version.  If LDFLAGS are set to "-Wl,-O1" the build fails and we get:

+ Entering Linux
  AS [x]   /var/tmp/portage/mol-0.9.70/work/mol-0.9.70/src/kmod/Linux/../build/_traps.o

rm: cannot remove `../build/mol.ko': No such file or directory

Of course the LDFLAGS are not pertinent to kernel modules (as noted), but they would be nice in the application itself and should be in any case suppressed when building the modules.

I looked into this one and I'll try to fix it as soon as I talked with vapier about a possible bug in flag-o-matic.eclass.

CFLAGS="-Wl,-O1"
LDFLAGS="-O1"

these are correct forms

LDFLAGS="-Wl,-O1"

this is not correct

Sorry, but I will have to reopen this.  Reference for the way I use LDFLAGS: http://forums.gentoo.org/viewtopic.php?t=67777 (subsequent posts do explain various differences in syntax).  Also see: http://forums.gentoo.org/viewtopic.php?t=231170 and http://forums.gentoo.org/viewtopic.php?t=226909 (plus references therein).

it doesnt matter how many forums you read, it's still wrong

Taviso could you update your guide at the forum with the correct syntax?

Comment 6 Alexander Skwar 2004-12-07 01:30:40 UTC

Hm, I'm a little confused. In this bug, it's written that

CFLAGS="-Wl,-O1"
LDFLAGS="-O1"

should be correct syntax. 

But when I set this, I cannot compile courier-authlib, which uses mysql_config.
I can only do so, when I don't add -Wl,-O1 to CFLAGS
