Hi, According to http://www.boost.org/users/history/version_1_63_0.html, 4.4.7 is the oldest compiler tested on linux, but on Windows, for example, 3.4.5 is mentioned. I cannot find page with the list of compiler officially supported, and it could be on a per library basis. Do you have another source of information ?

Hi,

According to the release notes, the oldest gcc that is officially supported is 4.4.7. I would assume that gcc 3.x is definitely not supported.

Cheers,

Hi,

In the serialization jam file (master), I see:

<toolset>gcc:<cxxflags>"-fvisibility=hidden -fvisibility-inlines-hidden" with no mention of gcc version number.

gcc-3.4.4, for one, does not support that option. Does that mean that the serialization library does not support the gcc-3.x serie ?

Thanks

Alain

By the way, I get the option even if I comment out that specific line.

Any idea why ?

Thanks

Still, I'm curious: why is serialization the only library using that option (on both archives and shared lib) ?

Also, is there syntax to limit the application of:

<toolset>gcc:<cxxflags>"-fvisibility=hidden -fvisibility-inlines-hidden"

starting with a specific gcc version ?

The predef library can be used to limit the application of any Boost Build properties based on minimum versions.

a) I don't know which is the earliest version of gcc to support visibility.

b) Even if I did, I don't know what boost build syntax I would use to specify this. - I've only been using boost build for 13 years.

c) FWIW I've never supported gcc versions 3.XX. There a number of issues such as support for wide characters.

d) If you want to suggest changes to jam files, I'll probably include them without testing them myself. So before submitting them, I'd appreciate it if you could run the serialization library tests yourself first. Well, I did a local test removing the feature, the lib itself builds but

Site stuck with 3.xx should probably stick to old version of boost I guess. Specially considering I have been using boost build only when I really had to and still haven't found its documentation.
