Hmm, I didn't have this problem when I built using gcc6.1 ... Maybe I didn't have libcurl installed on that box...

If you edit configure.ac and delete the following line:

AC_CHECK_LIB([curl], [curl_easy_init])

do a make distclean, then re-run ./configure

...does that fix the build? If so, something might be fishy in the libcurl headers with gcc6.

[mkrufky]

Based on what I've read in the following links:

• ::malloc has not been declared
• Thread: error: '::malloc' has not been declared

...this error is actually caused by the presence of AC_FUNC_MALLOC in configure.ac ... deleting that line should fix the build...

[mkrufky]

It turns out that libdvbtee has AC_FUNC_MALLOC in configure.ac but it isn't actually being used at all, and doesn't need to be there, so I have removed it from the master branch. I hope this fixes the cross build -- I haven't had a chance to test cross-build using gcc 6 yet.

seems fixed now thank you!

Thank YOU @rdp for reporting and testing :-)
