I installed the latest Cygwin to test EDK2 builds. One problem is
lack of Cygwin build instructions. Based on what I see, the Cygwin
should run from Windows shell and not bash shell. Here are the
commands I tried:
set CYGWIN_HOME=D:\tmp\cygwin64
set NASM_PREFIX=D:\edk2build\tools\nasm211\
cd /d D:\edk2build\edk2
Edk2Setup.bat
build.exe -p ShellPkg\ShellPkg.dsc -b RELEASE -t CYGGCC -n 16 -a IA32
The first problem with the existing Cygwin setup is that it does not
support Win64. That is because:
*_CYGGCC_*_MAKE_PATH = DEF(MS_VS_BIN)\nmake.exe
.. resolves to a hard-coded path Win32 path:
C:\Program Files\Microsoft Visual Studio 8\Vc\bin
.. which does not exist on Win64 machines (my recent proposal to replace
hard coded Windows paths with EV references was rejected).
I don't see much point in setting up a Win32 test because quite a few
Windows users have switched to Win64. So instead I work around this
problem by modifying the hard-coded path. The next problem is:
NMAKE : fatal error U1077:
'"c:/cygwin/opt/tiano/i386-tiano-pe/i386-tiano-pe/bin/gcc"'
Another hard-coded Windows path. The name suggests a custom built gcc. Cygwin
doesn't ship with a compiler by this name. To work around I change it to the
Cygwin
native gcc 4.8.3 compiler and try again:
cc1.exe: error while loading shared libraries: ?: cannot open shared object
file
To resolve this, I add to the Path:
set path=D:\tmp\cygwin64\usr\i686-pc-cygwin\sys-root\usr\bin;%Path%
Next problem:
cygwin warning:
MS-DOS style path detected:
d:\edk2build\edk2\ShellPkg\Library\UefiFileHandleLib\UefiFileHandleLib.c
Preferred POSIX equivalent is:
/cygdrive/d/edk2build/edk2/ShellPkg/Library/UefiFileHandleLib/UefiFileHandleLib.c
CYGWIN environment variable option "nodosfilewarning" turns off this warning.
Consult the user's guide for more details about POSIX paths:
http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
Solution: set CYGWIN=nodosfilewarning
Next problem: The first C file compiles without any error logged, yet
gcc comes back with return code 1 and no object file is written. The
cause is not obvious.
Next I try from the Cygwin bash shell:
$ cd /cygdrive/d/edk2build/edk2
. edksetup.sh
$ build -p ShellPkg/ShellPkg.dsc -b RELEASE -t CYGGCC -n 16 -a IA32
Result is:
build.py...
: error 7000: Failed to start command
C:\WINDDK\3790.1830\bin\x86\nmake.exe
Same happens if Cygwin make is used:
build.py...
: error 7000: Failed to start command
c:/cygwin/bin\make.exe
Work around: change tools_def: use cygwin style paths:
DEFINE CYGWIN_BIN = /cygdrive/d/tmp/cygwin64/bin/
DEFINE CYGWIN_BINIA32 = /cygdrive/d/tmp/cygwin64/bin/
DEFINE CYGWIN_BINX64 = /cygdrive/d/tmp/cygwin64/bin/
etc
Result is better. Some C files compile, then:
/cygdrive/d/edk2build/edk2/Build/Shell/RELEASE_CYGGCC/IA32/MdePkg/Library/BaseLib/BaseLib/OUTPUT/Ia32/EnablePaging64.iii:40:
Error: unsupported instruction `mov'
I need to set this test aside for the moment. I am sure Cygwin
can be made to work. But it seems like quite a few changes are
needed. Disclaimer: I don't use Cygwin much. maybe someone more
familiar with Cygwin could get it going more easily.
Thanks,
Scott

Before deprecate those tool chains, I still want to make them work with the
updated Build Tools.
If there is no one to use them, I think we can remove them. Could you raise
your proposal in this mail list to collect more feedbacks?
Thanks

Can we change CYGGCC like this?
I basically think CYGGCC is pointless, but I thought that the strange fact that
it used nmake was one of the main characteristics of it.
And, if we can change a toolchain so drastically, why can't we deprecate
toolchains? (For example, I think we should just deprecate CYGGCC and ELFGCC...)
