/tmp is not mounted to %TEMP%

[orgads]

It used to be in MsysGit.

[PhilipOakley]

There has been quite some discussion around the tmp/TEMP directories you may want to look at in the various issue/PR discussions. e.g. #123

How is this affecting you (do you have an example to help with a Minimal, Complete and Verifiable Example ;-)

[PhilipOakley]

For searching, try putting "%TEMP% in:title,body" in the filter box of the issues page (you (& I) learn something every day) or "%TEMP% in:title,body,comment" etc. See the https://help.github.com/articles/searching-issues/ page for some examples

[dscho]

Since %TEMP% is user-dependent, I am not quite sure how that would be encoded properly in an fstab (the file where drive mappings are specified for Cygwin/MSys2). There might already be an option for that, or it will require appropriate changes in msys-2.0.dll -- accompanied by the corresponding change in the git-extra package.

@orgads if you are interested in tackling this, please have a look at this description how to build the MSys2 runtime ("msys-2.0.dll").

[dscho]

@orgads I was hoping to interest you in this issue, so I implemented a very first version of a topic branch to help with this issue, but I need your help now: could you have a look, test, and see whether you can do something about the output of mount.exe when called without arguments?

[orgads]

@dscho Thanks for your efforts. I'm sorry for not being responsive lately. I was loaded with work.

I'll try to get to this on next Monday.

[dscho]

@orgads thanks. Please note that my current plan is to release Git for Windows on Monday.

[dscho]

@orgads out of curiosity: did you work on this yet?

[orgads]

I won't have time today. Hopefully tomorrow. Let's leave it for the next
release.

I just merged an updated version of git-for-windows/msys2-runtime#9. It lists /tmp/ correctly in the mount output.

[orgads]

Great!

I actually tried to build msys2-runtime but couldn't get it to compile (some fpermissive errors...)

[dscho]

You have to build it from the MSys2 shell, i.e. start C:\git-sdk-64\msys2_shell.bat. Otherwise you are in a MINGW instead of an MSYS build environment.

[orgads]

That's what I did. It starts building fine, but after a few minutes I'm getting many errors such as:

c++wrap -pipe -O2 -g -ggdb -fno-rtti -fno-exceptions -fno-use-cxa-atexit -Wall -Wstrict-aliasing -Wwrite-strings -fno-common -pipe -fbuiltin -fmessage-length=0 -MMD -Werror -fmerge-constants -ftracer -mcmodel=small -c -o dlfcn.o /usr/src/MSYS2-packages/msys2-runtime/src/msys2-runtime/winsup/cygwin/dlfcn.cc

 void __stdcall close_all_files (bool = false);

[dscho]

Oh... slaps-his-head. To build the msys2-runtime, actually, any MSys2 package, you need to call

pacman -Sy base-devel binutils

once, to initialize the build system.

[orgads]

@dscho Thanks. I already did that. I'm building by running makepkg in msys2-runtime directory in MSYS2-packages. Should I use something else?

[dscho]

no, that's correct. Maybe your PATH is wrong? What does which c++wrap.exe say?

[orgads]

which: no c++wrap.exe in (...my path...)

[dscho]

Hmm, neither is it in the PATH here. So that means that something went wrong at configure time.

[dscho]

Okay, so this is the output here:

$ echo $MSYSTEM
MSYS
$ uname -a
MSYS_NT-6.3 dscho 2.1.2(0.288/5/3) 2015-05-25 15:48 x86_64 Msys
$ cd  /usr/src/MSYS2-packages/msys2-runtime/src/build-x86_64-pc-msys/x86_64-pc-msys/winsup/cygwin
$ rm -f dlfcn.o && make dflcn.o
c++wrap -pipe -O2 -g -ggdb -fno-rtti -fno-exceptions -fno-use-cxa-atexit -Wall -Wstrict-aliasing -Wwrite-strings -fno-common -pipe -fbuiltin -fmessage-length=0 -MMD -Werror -fmerge-constants -ftracer -mcmodel=small -c -o dlfcn.o /usr/src/MSYS2-packages/msys2-runtime/src/msys2-runtime/winsup/cygwin/dlfcn.cc

And it works correctly here, obviously... Maybe you can spot differences in your setup?

[orgads]

It's exactly the same.

Yours?

Finally found the reason for the compilation error: git-for-windows/msys2-runtime#12
