When installing PHP 4.3 on my system running GCC 2.95.3, I get the following output. This is obviously incorrect. If you need any further info, please ask. I have tested the PHP configure script outside the ebuild system, and it worked just fine, properly detecting that GCC was not a cross compiler. I also tried removing the -pipe and -O3 flags from the build options, and it still had the same problem. arsenic root # emerge php Calculating dependencies ...done! >>> emerge (1 of 1) dev-php/php-4.3.0-r2 to / >>> md5 ;-) php-4.3.0.tar.bz2 >>> Unpacking source... >>> Unpacking php-4.3.0.tar.bz2 >>> Source unpacked. ssl gdbm mysql truetype jpeg Compiling imap with SSL support libwww flash xml2 crypt creating cache ./config.cache checking for Cygwin environment... no checking for mingw32 environment... no checking for working sed... sed checking host system type... i686-pc-linux-gnu Updated php_version.h checking for gcc... gcc checking whether the C compiler (gcc -march=i686 -O3 -pipe ) works... yes checking whether the C compiler (gcc -march=i686 -O3 -pipe ) is a cross-compiler... yes checking whether we are using GNU C... yes checking whether gcc accepts -g... yes checking whether gcc and cc understand -c and -o together... yes checking how to run the C preprocessor... gcc -E checking for AIX... no checking if compiler supports -R... no checking if compiler supports -Wl,-rpath,... yes checking for ranlib... ranlib checking whether ln -s works... yes checking for gawk... gawk checking for bison... bison -y checking bison version... 1.35 (ok) checking for flex... flex checking for yywrap in -lfl... yes checking lex output file root... lex.yy checking whether yytext is a pointer... yes checking for working const... yes checking flex version... 2.5.4 (ok) checking for pthreads_cflags... checking for pthreads_lib...

Any progress yet?
Matthew are you running the newest gcc-config?

I'm using gcc-config 1.3.1
Okay, just installed gcc-config 1.3.1, and I'm getting exactly the same behavior.
Just a note: I just had to restart my Apache server, which forced me to figure out a way to get PHP to rebuild. (My old PHP was linked against a library that no longer exists on my system...) I managed to get it to work by executing the ebuild one step at a time except for the configure step. I forced the ebuild to just output the configure line it would have run, and ran it myself on the portage working directory. It worked properly, and I was able to continue with the step-by-step ebuild. Just in case, I'm going to re-emerge Python and Portage and see if that fixes the problem, since it's apparently some kind of issue with the Portage build environment.
Works fine here with gcc-2.95.3 ------------------------------ nosferatu php-4.3.0 # epm -q gcc gcc-config gcc-3.2.1-r7 gcc-2.95.3-r8 gcc-config-1.3.1 nosferatu php-4.3.0 #
I'm willing to let Ryan in to take a look at my box firsthand, if you want. As I said, I've found a workaround, but it's a pain in the butt to do, so I'd like to get this solved.
Matthew: email me at rphillips@gentoo.org
Include output of 'gcc -v' please.
arsenic root # gcc -v Reading specs from /usr/lib/gcc-lib/i686-pc-linux-gnu/2.95.3/specs gcc version 2.95.3 20010315 (release) Also, Ryan logged in and did a lot of poking around. The problem is somehow related to the 'xml' use flag, and the portage environment. I'm not sure what all he discovered, so you'll have to get the details from him. But, for the time being, I've got a working system.
I unmasked mysql-4.0.10 to install it on my box, and trying to rebuild PHP (4.3.1) afterwards, I get the same error about cross-compiling. I also tried the latest PHP-4.3.1-r1, with the same result. Removing -O3/-pipe from the CFLAGS has no effect.

solution found! it's because of net-libs/libwww and >=mysql-4 net-libs/libwww contains: /usr/lib/libxmlparse.so /usr/lib/libxmltok.so which both link against libmysqlclient.so.10 ... I had mysql-3 installed, but upgraded to mysql-4 because i needed some advanced features only in the 4 line. then, going to build my php, it was failing with that error. when the PHP configure tries to build it's conftest for cross complining it links against xmltok and xmlparse. since then link to libmysqlclient.so.10 and that file no longer exists (it became libmysqlclient.so.12 with mysql-4) the conftest wouldn't run, and the way the script was set up, it detected this as a cross-compiler. the ebuilds for net-libs/libwww all contain: !>=mysql-4 the change to exclude mysql-4 was made because of bug 15099 I'm going to write up some fixes to libwww and submit them to w3c for this. I've temporarily done: USE="-mysql" emerge net-libs/libwww so that I can get to rebuilding my PHP
Great! Thanks for all the info. I'll keep this in mind in the future.

glad you guys found the answer :)
I haven't got to writing any patches for libwww yet so it can compile, but can something more sensible be done with the libwww ebuild so that it only compiles in support for MySQL if the version is less than 4 ? and DOESN'T give a warning otherwise.

I didn't found anything about php cross compiling error during my search and didn't notice this bug report before posting the bug 16954. Sorry and thank you to you all.
Closing bug properly.
