Hello,
I followed instructions at http://www.devnewz.com/090902b.html about setting up correctly a VC++ project for building an extension, and I tried to build the provided "hello world" example.
Helas, I still get this "unresolved external symbol" kind of linker errors :
Compiling... test1.cpp [warnings about externals] Linking... test1.obj : error LNK2001: unresolved external symbol _zend_printf Release_TS/php_test1.dll : fatal error LNK1120: 1 unresolved externals Error executing link.exe.
Is there anything I missed ? Except that I use VC++ 5 SP3 and php4ts.lib of latest 4.3.7 in stead of VC++ 6 and 4.2, I don't see any meaningful configuration discrepancy...
Below the first message that I - apparently wrongly and to no avail - sent to php-internals because I thought it was a Zend Engine settings problem.
Any help welcome ; I'm sure a lot of people here can help me by diverting some ticks of their precious brain processing time :D

Hello,
Althought I usually try to avoid putting my fingers in a C/C++ IDE, I'm trying to build a DLL on Win32 via porting the code (it's the php_bwcache.dll, if you want to know)
I managed to get rid of all compile errors & warnings, but now I have linker errors that I feel are due to Zend Engine settings in the provided PHP/Windows binaries.
Even when successfully linking statically to php4ts.lib from latest & stable PHP 4.3.7, I still receive those linking errors and can't get rid of them :
--------------------Configuration: bwcache - Win32 Release_TS PHP--------------------
Compiling...
bware_cache.c
Linking...
Creating library php_bwcache.lib and object php_bwcache.exp
bware_cache.obj : error LNK2001: unresolved external symbol _compiler_globals_id
bware_cache.obj : error LNK2001: unresolved external symbol _executor_globals_id
bware_cache.obj : error LNK2001: unresolved external symbol _empty_string
bware_cache.obj : error LNK2001: unresolved external symbol _zend_compile_file
php_bwcache.dll : fatal error LNK1120: 4 unresolved externals
Error executing link.exe.
Creating browse info file...
php_bwcache.dll - 5 error(s), 0 warning(s) ----------------
I upgraded my VC++ 5.0 compiler to SP3 and don't think this is an issue
I checked that compiler_globals_id (for instance) is indeed defined in the php4ts.dll (and so should be in the .lib import lib)
Any advice welcome on those strange "unresolved externals",
Thanks & Regards,
VGR
