with emerge : C++ compiler cannot create executables

Message

manouchk · Post by **manouchk** » Mon Mar 24, 2008 8:27 am

Hi,

I'm preparing a new ebuild for objcryst-fox (http://objcryst.sourceforge.net/) and I had a problem when trying to emerge the new ebuild I prepared (http://emmanuelfavrenicolin.free.fr/Pub ... 962.ebuild).

At some stage, during a "./configure" emerging this program would end up by :
cd /home/portage_tmp/portage/sci-physics/objcryst-fox-1.7.5.1-r962/w
ork/Fox-1.7.5.1-R962/Fox/src/../../fftw && ./configure --enable-sing

See `config.log' for more details.

If I go to the same place and manually run ./configure I don't see this error. What could be the problem?

Something like this can happen if your CFLAGS of CXXFLAGS are incorrect. Please post the output of emerge --info

This should tell you.

Yesterday I had tried to reinstall libstdc++-v3-3.3.6 and libtool-1.5.26 but it didn't resolve the problem.
TOday, I tried compiling without optimization (USE=-opt ) but the problem was still there.

Now I'm trying this : uninstalling old automake and reinstalling the last automake (1.10) and I'm compiling again (it's quite long to compile here with a dothan 1.5 GHz).

Why don't you post the relevent part of the config.log
instead of randomly re-emerging packages? Without
this information we won't be able to help you.

Well to be frank you thought wrong. That error message could be from a whole bunch of things. It doesn't narrow it down whatsoever.

From the config.log it's crapping out with saying -fcxxflags isn't a valid option for gcc. And a quick google search indicates this is something to do with them using backticks when they shouldn't so it's trying to execute something that shouldn't (as in the backticks work great in a shell but when it's not being run inside a shell since it's inside a part of the portage command). And I mean that it's a problem with the configure script being bad from the looks of it.

manouchk · Post by **manouchk** » Wed Mar 26, 2008 10:52 am

In the config.log after the error it gives the program

configure: failed program was:

and later we find that the variable CXXFLAGS is :

Code: Select all

CXXFLAGS='-I/home/portage_tmp/portage/sci-physics/objcryst-fox-1.7.5.1-r962/work/Fox-1.7.5.1-R962/Fox/src/../../ObjCryst/.. -I./ -I/include -I/home/portage_tmp/portage/sci-physics/objcryst-fox-1.7.5.1-r962/work/Fox-1.7.5.1-R962/Fox/src/../../ObjCryst -I/home/portage_tmp/portage/sci-physics/objcryst-fox-1.7.5.1-r962/work/Fox-1.7.5.1-R962/Fox/src/../../static-libs/include -DOBJCRYST_GL -I/usr/X11R6/include -IGL -DHAVE_GLUT -D__WX__CRYST__ `/home/portage_tmp/portage/sci-physics/objcryst-fox-1.7.5.1-r962/work/Fox-1.7.5.1-R962/Fox/src/../../ObjCryst/../static-libs/bin/wx-config --cxxflags` -DHAVE_FFTW '

If I catch all line with CXXFLAGS in configure we have:

If I run the command between `` it works but it is not in portage is it the problem?

running in a terminal :
/home/portage_tmp/portage/sci-physics/objcryst-fox-1.7.5.1-r962/work/Fox-1.7.5.1-R962/Fox/src/../../ObjCryst/../static-libs/bin/wx-config --cxxflags

gives me :

Like I said, the configure works fine when the whole thing is run from a terminal/shell. The configure script has something in it that uses backticks which only function correctly in a terminal. Since portage isn't running the configure inside a terminal the backticks don't function (which is the expected result).

So maybe send a message to the upstream devs about it. Or see if you can patch the confgure script yourself.

Exactly. Thank you. Let say if I cna localise the problem tonight

Well, I'm having some difficulties with make script, because I don't how it works. Are there good material on makefile?

I modified the makefile that causes problems but, I had an unexpected results. I tried to use variables to avoid use of backticks.

I basically modified like this :

$(VAR) get the string content of VAR execute "as if" it was running in a shell and return the result of the command as a string

I already entered in contact with the dev which happens to be my brother but he is lately quite busy!

Anyway I progressed using variables but then I reach another error later in the Makefile

If I look at what's told to be done in makefile here : http://wiki.wxwidgets.org/Makefile

It just say to use backtics or variables!

If I use

CXXFLAGS = $(shell `which wx-config` --cxxflags)

it seems to work!
