Hi,
Just tried to compile Inkscape trunk on my spanking new laptop (replacing my 6.5 year old one). It failed in 2geom with an error from the boost library. I used Fedora 15 beta which has boost 1.46 and gcc 4.6. The error message is:

Any clues?

The same error was reported in #inkscape (irc) by a user on Arch linux, compiling inkscape (trunk as well as the ocal branch) with GCC 4.6 (no solution known so far).

Hi, Just tried to compile Inkscape trunk on my spanking new laptop (replacing my 6.5 year old one). It failed in 2geom with an error from the boost library. I used Fedora 15 beta which has boost 1.46 and gcc 4.6. The error message is:
Looks like the new GCC version changed its mind about whether HShear and VShear satisfy the TransformConcept. As a workaround, comment out the lines: BOOST_CONCEPT_ASSERT((TransformConcept<HShear>)); BOOST_CONCEPT_ASSERT((TransformConcept<VShear>)); in src/2geom/transforms.cpp.
The offending line is line 212 in src/2geom/transforms.h - we are trying to return a non-const reference a const object. I don't really remember why I wrote it this way. Can you try changing the return statement to "return *this"?

Now also reported for Ubuntu Natty with libboost_1.42 and gcc_4.6.0: https://bugs.launchpad.net/inkscape/+bug/779016
Workaround and proposed fix failed on debian sid (GCC 4.6) - as reported on #inkscape (irc).

Attempt #2: try changing the return statement at 2geom/transforms.h:212 to "return static_cast<S &>(*this);" This works with GCC 4.5, but so did "return *static_cast<S const*>(this);" Regards, Krzysztof

Confirmed to work with GCC 4.6 on Debian Sid (compiles without failure, initial tests with tools and transforms ok).

Thanks everyone! It now compiles for me.

attached the diff that let it compile under fedora 15. I have a fefdora on my virtualbox. Possibly mkinstalldirs should not be under versioncontrol.
