lex.yy.cpp:(.text+0xac1): undefined reference to `yylval'

[arrummzen]

I am trying to compile a copy of vegastrike that I copied out of svn last night. When I run make vegastrike I get a link error as shown below.

make: *** [vegastrike] Error 1

Are you sure you want my config.log file? It is huge... is there a specific subsection I could paste?

Thank you for your time,
Arrummzen

[JasonStiletto]

in src/cmd/script/c_alike/lex.yy.cpp
around line 358

you have

extern int yylineno;
int yylineno = 1;

change it to

extern int yylineno = 1;
//int yyline = 1;

and you'll get past that error.

c++ isn't really one of the languages I'm good at though.

[ace123]

Can you post the output of g++ -v

Also, make sure that you are at the latest SVN revision.

[JasonStiletto]

in my case

likewise, using latest SVN as of this morning, been a while sense it's compiled successfully on this box, but the 4.x.x flavors of gcc are supposed to be a bit more strict about certain things.

[ace123]

That is incredibly odd...

For me, lex.yy.cpp is completely empty (just a filler file for the compile script I guess).

It's been empty in Subversion for a really long time.

Maybe just try emptying that file and see if it then compiles.

You may also want to look at

Code: Select all

svn status

and look for modified files.

[JasonStiletto]

Well, that's strange. it is empty to begin with, empty (I think) after configure, empty during make, then at some point in make it becomes... not empty.

cd src/cmd/script/c_alike/
rm lex.yy.cpp
touch lex.yy.cpp

cd ~/vegastrike
make vegastrike

and it finishes compiling?

I'll see if I can find out when it comes to be a bit better.

This is because flex is run onto the c_alike;lex file (in vegastrike/src/cmd/script/c_alike/ ), thus regenerating a new lex.yy.cpp each time.
I've posted a patch (against svn 10724) in this group (previous thread, about SharedPool.cpp deps...),.

Seems also that ace123 will add a fix in the next svn rev.

Before applying the patch, don't forget to do (from the vegatrike top dir)
svn revert -R src/cmd/script/c_alike
then, from the same vegastrike directory:
patch -p0 < trunk_vegastrike_pmx_toplevel_10724.diff.txt

Should do the trick ...

[pmx]

I just checked the svn repository, the problem have been fixed there.
So, dont bother with my patch file, just do a svn update ...
