pango: segfault in libpangoft2-1.0-0.dll #1265

Shreeshrii · 2016-03-31T08:06:35Z

Is a debug version of pango available? Tesseract training tools (text2image) segfault when used under MSYS2. They work fine under linux, the problem seems to be with libpangoft2-1.0-0.dll

I tried to build it with enable-debug, but that process is getting errors too.

Update packages with pacman -Syuu to get rebuilded GCC and downgraded BINUTILS and try again.

Alex,
I am still getting the segfault after updating packages with pacman -Syuu

Alexpux · 2016-03-31T17:34:39Z

Seems you have some missing packages for build. Install gtk-doc package

Shreeshrii · 2016-03-31T17:53:21Z

I have all of the packages listed in PKGBUILD. Are any others needed? makedepends=("${MINGW_PACKAGE_PREFIX}-gcc" "${MINGW_PACKAGE_PREFIX}-pkg-config" "${MINGW_PACKAGE_PREFIX}-gobject-introspection") depends=("${MINGW_PACKAGE_PREFIX}-gcc-libs" "${MINGW_PACKAGE_PREFIX}-cairo" "${MINGW_PACKAGE_PREFIX}-freetype" "${MINGW_PACKAGE_PREFIX}-fontconfig" "${MINGW_PACKAGE_PREFIX}-glib2" "${MINGW_PACKAGE_PREFIX}-harfbuzz")

Alexpux · 2016-03-31T17:54:58Z

try install gtk-doc as I told you.

mati865 · 2016-03-31T18:57:19Z

After installing gtk-doc prepare() pass. I'll edit comment when build() finish to let you know if everything is fine.

EDIT: Builds fine.

Shreeshrii · 2016-04-01T16:25:43Z

Alex, I was able to build pango with debug. Thank you!

Alexpux · 2016-04-09T07:39:40Z

Is it solved?

mati865 · 2016-04-09T11:24:46Z

Probably not related to msys2 amitdo/text2tif-2016#1

Alexpux · 2016-04-09T11:31:01Z

we not have text2tif executable in our packages.

Shreeshrii · 2016-04-09T11:36:41Z

Thanks. Appreciate the help.

You can close this.

@Shreeshrii, you solve this?

Shreeshrii · 2016-04-09T13:43:09Z

I think it was application problem. Debug version of pango helped find it.

the original code of text2image from tesseract-ocr also has the same
problem.

Please see
amitdo/text2tif-2016@b055d43

Amit @amitdo has just added a workaround to avoid the crash under
msys2/mingw64 -

It works under linux and cygwin, if you have any suggestions please let us
know.

I will pull request the changes done in text2tif to tesseract sometime this month.
