Description Ulrich Drepper 2003-09-09 21:33:27 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5b) Gecko/20030904
Firebird/0.6.1+ StumbleUpon/1.83

Description of problem:
The C++ compiler cannot locate the C++ headers.  libstdc++-ssa-devel is installed.

Version-Release number of selected component (if applicable):
gcc-c++-ssa-3.5ssa-0.20030801.36

How reproducible:
Always

Steps to Reproduce:
Run g++-ssa -o t t.cc with this code

#include <iostream>
int
main ()
{
  std::cout << "hello world" << std::endl;
}


Actual Results:  t.cc:1:20: iostream: No such file or directory
t.cc: In function `int main()':
t.cc:5: error: `cout' is not a member of `std'
t.cc:5: error: `endl' is not a member of `std'


Expected Results:  Clean compile

Additional info:

The compiler looks at the following places for the file:

/usr/local/include/iostream.gch
/usr/local/include/iostream
/usr/include/iostream.gch
/usr/include/iostream

That's it.  No other files are looked at.

Comment 1 Ulrich Drepper 2003-09-09 21:51:44 UTC
Jakub suggested running this:

$  g++-ssa  -v -E -xc++ /dev/null 2>&1 | grep include
ignoring nonexistent directory "/lib/include/c++/3.5-tree-ssa"
ignoring nonexistent directory "/lib/include/c++/3.5-tree-ssa/ia64-redhat-linux-gnu"
ignoring nonexistent directory "/lib/include/c++/3.5-tree-ssa/backward"
ignoring nonexistent directory "/lib/ia64-redhat-linux-gnu/include"
#include "..." search starts here:
#include <...> search starts here:
 /usr/local/include
 /lib/ssa/gcc-lib/ia64-redhat-linux-gnu/3.5-tree-ssa/include
 /usr/include


I.e., it's "just" the wrong prefix with which gcc is compiled.

Comment 2 Frank Ch. Eigler 2003-09-10 17:37:04 UTC
This appears to be caused by cc1plus looking for its
/usr/include/c++ headers by means of relative traversal
from the gcc-lib directory:

/lib/ssa/gcc-lib/i386-redhat-linux-gnu/3.5-tree-ssa/../../../../include/c++/3.5-tree-ssa

If $libdir=/usr/lib, this works
If $libdir=/lib/ssa, this works not


Comment 3 Diego Novillo 2003-09-11 14:52:43 UTC
I hacked the gcc-ssa.spec file to force g++ includes into /lib/ssa.  The new .37
release should work.

Comment 4 Ulrich Drepper 2003-09-12 18:55:21 UTC
I tested .38 and it indeed works, at least for my test cases.
