Re: Issues while building PG in MS Windows, using MSYS2 and MinGW-w64

Hi Tom Lane,

Thanks for the help.

I had extracted PG using WinZip outside of MSYS2, and it was causing many of the errors, may be due to some errors in file attributes. So I unpacked the source tarball within the shell itself(using gunzip and tar), and I could fix many errors.

Now new errors are popping up. I've compared the config file with the file given in the URL, but I couldn't fix this yet.

The current error is basically due to the fact that, PUTENVPROC macro is defined to empty.

Config output and make error output are uploaded here https://gist.github.com/codercet/760ae3b0337144059570ccfc06e2a847

config.log is available here https://gist.github.com/codercet/725cc5fdd0acfbf5193d891bffb4dfda

The error output while doing make is

gcc -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -fexcess-precision=standard -g -std=c11 -I../../src/port -DFRONTEND -I../../src/include -I./src/include/port/win32 -DEXEC_BACKEND "-I../../src/include/port/win32" -DBUILDING_DLL -c -o win32env.o win32env.c

I don't know anything about mingw, but from the first error message you

showed, I'd venture that configure failed to fill in pg_config_ext.h

correctly. It should have put in a line like

#define PG_INT64_TYPE long long int

and evidently it hasn't. This suggests that there's something wrong

with one of the text-processing tools it uses, such as "sed". You

might look into config.log and see if there are any relevant-looking

error messages (probably down near the end). Also, try comparing

your configure text output and config.log to those of one of our

buildfarm machines that's using mingw successfully, such as

https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=jacana&dt=2018-04-27%2012%3A19%3A49

(the "config" and "configure" links on that page are what to compare to).

Hm ... I notice that jacana's been set up so that it explicitly

gives configure a --host setting instead of letting configure work

that out. No idea if that was really necessary or not.
