Description:
------------
I try to build the ibm_db2 pecl extension v2.1.3 with PHP 8.0.9 on Windows10-x64 with Visual-Studio-2019 Community Edition.

But the build of php itself fails before reaching the ibm_db2.c compilation.

I follow the steps at this page:
https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2

I show the steps I took, in separate section below.

nmake fails with a linker error:

"fatal error C1900: Il mismatch between 'P1' version '202110113' and 'P2 version '20190715'


The nmake log file has this at the end:

    rc /nologo /fo D:\php-sdk\phpdev\vs16\x64\phpdev\vs16\x64\phpdev\vs16\x64\php-src-php-8.0.9\x64\Release_TS\php8ts.dll.res /d FILE_DESCRIPTION="\"PHP Script Interpreter\""  /d FILE_NAME="\"php8ts.dll\"" /d PRODUCT_NAME="\"PHP Script Interpreter\""  /ID:\php-sdk\phpdev\vs16\x64\phpdev\vs16\x64\phpdev\vs16\x64\php-src-php-8.0.9\x64\Release_TS /d MC_INCLUDE="\"D:\php-sdk\phpdev\vs16\x64\phpdev\vs16\x64\phpdev\vs16\x64\php-src-php-8.0.9\x64\Release_TS\wsyslog.rc\""  win32\build\template.rc

Stop.



Test script:
---------------
d:
mkdir d:\tmp


rd /s /q d:\php-sdk
git clone https://github.com/Microsoft/php-sdk-binary-tools.git d:\php-sdk
cd /d d:\php-sdk
git checkout php-sdk-2.2.0
phpsdk-vs16-x64.bat    
phpsdk_buildtree phpdev  
unzip -q %userprofile%\downloads\php-src-php-8.0.9.zip
mkdir pecl
copy %userprofile%\downloads\pecl-database-ibm_db2-RELEASE_2_1_3.tar.gz .\pecl
cd pecl
gzip -d *
tar -xf *.tar
edit the config.w32 to replace db2cli.lib by db2cli64.lib for clidriver
edit the ibm_db2.c to replace " ulong " by " unsigned long " on 3 lines (bugfix)
cd ..\php-src-php-8.0.9
phpsdk_deps -u

--verify %LIB% includes e:\db2\lib
--verify %INCLUDE% includes e:db2\include
--verify PATH includes e:\db2\bin

buildconf
configure --help | find /i "ibm" 
configure --enable-cli --with-ibm_db2=shared,e:\db2 1>\tmp\configure.log 2>&1

 nmake 1>\tmp\nmake1.log 2>&1


Expected result:
----------------
Was expecting a successful build for v8.0.9 (the build of 7.4.22 on a different hostname was successful).

Actual result:
--------------
libiconv_a.lib(iconv1.obj) : MSIL .netmodule or module compiled with /GL found; restarting link with /LTCG; add /LTCG to the link command line to improve linker performance
fatal error C1900: Il mismatch between 'P1' version '20210113' and 'P2' version '20190715'

What's the exact version of your VS 2019 (should be something like
16.10.3)?
 [2021-08-06 11:43 UTC] mike_itguy at Yahoo dot co dot uk
Visual Studio 2019 community edition, version 16.7.2
in the phpsdk starter script the msvc version reported ist 14.27.29111

You need to update to latest (16.10.4), or rebuild some dependecy
libraries.  I suggest you do the former.  If there are C1047 errors
during build, you can work around by

    set LDFLAGS=/d2:-AllowCompatibleILVersions

and running buildconf etc. again.

Also note that replacing `ulong` with `unsigned long` is not wrong,
but the improved solution of the PR[1] is preferable.

thank you. I will update the VisualStudio2019 to 16.10.4 current and retry.
 [2021-08-06 13:50 UTC] mike_itguy at yahoo dot com
Updated the VS2019 to 16.10.4, and started the build from scratch.
I did not change the LDFLAGS.
This time the build completed without errors.
Many thanks.
