Error reproduced for ICC Debug+Shared builds only, and not reproduced, if:
used '/O2' key instead of '/Od'-'/O1'
OR
'-Zi' key removed
from CXXFLAGS environment variable.
Error was reported before in other threads: QTBUG-48062 (2015), Apache C++ Standard Library (2006), Win32 -MD link error (2003), Is JPEG2000 supported (2006), etc.
Environment:
- Windows 10 x64,
- IPSXE 2017 Update 2,
- VS 2015 Update 3,
- MSYS2 20161025,
- ICU4C 58.2.
UPDATE: Steps to reproduce error using shell.
1. Install MSYS2 to some directory (see installation and configuration in case troubles), so path to its files won't contain spaces, e.g. 'c:\ProgramData\Msys64', and:
- run shell using command 'mingw64.exe' from MSYS2 installation folder,
- upgrade using command 'pacman -Syuu' (could require few runs, until all components be upgraded),
- install additional packages ('make' utility) using command 'pacman -S make',
- delete file 'usr\bin\link.exe' from MSYS2 installation folder (or it would conflict with MSVC linker),
2. Extract ICU4C 58.2 sources to some directory, e.g. 'c:\TEST' so it would look like:
c:\TEST\icu\as_is\ ... c:\TEST\icu\readme.html
3. Run 'Compiler 17.0 Update 2 for Intel 64 Visual Studio 2015 environment' command prompt from Windows Start menu, and run commands:
set MSYSTEM=MINGW64 set PATH=c:\ProgramData\Msys64\usr\bin;%PATH% sh cd /c/TEST/icu/source (CC="icl" CXX="icl" CFLAGS="-Od -MDd" CXXFLAGS="-Od -Zi -MDd" ./configure --enable-debug --disable-release --enable-shared --disable-static && make) [command 'make -j<n>' could also be used to speedup build]
which reproduce error:
A previous version ICU4C 54.1 (Oct, 2014) from ICU-Project archives also reproduce this error.
Didn't tested on earlier versions, since they didn't provide support for MSYS2. Wherein file 'runConfigureICU' in that versions, e.g. ICU4C 38 (Sep, 2007) contain comment:
# The Intel compiler has optimization bugs. So we disable optimization.
Although it relate to opposite issue and not reproduced in recent versions, it indicate, that ICU build errors, related ICC optimization flags on Windows, are "a long-playing record".
