[Pkg-fonts-devel] Bug#1114734: libwoff1: Debug logging to stderr is enabled for the shared library

[Dennis Prochko]

Package: libwoff1
Version: 1.0.2-2
Severity: normal
X-Debbugs-Cc: dennis.prochko at gmail.com

Dear Maintainer,

When I link this library to my application and use its ConvertTTFToWOFF2
function, it prints debug information to stderr, like:

"Compressed 100000 to 20000"

It happened because the library code checks for defined symbol
"FONT_COMPRESSION_BIN" which is normally set for console application
only and should not be defined for the library (the same code package
contains both console app and the library code).

The build system uses CMake, which defines this in the CMakeLists.txt
file as follows:

# Build options
option(NOISY_LOGGING "Noisy logging" ON)

The problem is that in the Debian package this option is defined both for
the console utility and for building the library, while when building
the library this option should be disabled.

Outputting debug information to the stderr may break some applications
that do not expect it. I have to statically link my app with the library
source code instead of enjoying the official debian package, for example.

It would be really nice if you could disable noisy logging at least for the library.
