wcstombs error when compiling package with Debian/Ubuntu
Dear Prof. Ripley, Thank you for this extensive explanation. The compiler version of OpenSUSE11.1 is "gcc version 4.3.2" whereas Ubuntu uses "gcc 4.4.1". Interestingly, the first complaint was a Debian testing (squeeze) user with "gcc-4.3". Since my package depends on ROOT I have assumed that <stdlib.h> was declared in their headers, which is only the case for Sun. Thus it seems that I need to add <cstdlib> to my respective implementation files. Best regards Christian

Such errors are common when people use older versions of g++ to write their C++ code. Later versions of g++ have somewhat stricter conformance to the C++ standards and catch some lax usage: we've seen it quite a lot for g++ 4.4.x and even more for pre-4.5.0. In all the cases I have seen this message indicates a missing header. wcstombs is a C99 function declared in <stdlib.h>: given that this looks like a C++ error message, did you include its C++ version, <cstdlib>? Note that Mac OS X and (32-bit) WinXP are using g++ 4.2.x. Also, what other headers a particular header includes is OS-dependent (and maybe even compiler-dependent): we have had a lot of trouble recently with <stdint.h> that some OSes (especially MinGW32) include from more common headers and some do not. So this may be an OS issue but a compiler-version issue is more likely. On Wed, 10 Feb 2010, cstrato wrote:
Dear Debian/Ubuntu experts, For the second time users of my BioC package reported problems when trying to compile it on Debian/Ubuntu. The error is always the same: "'wcstombs' was not declared in this scope", see: https://www.stat.math.ethz.ch/pipermail/bioconductor/2010-February/031739.html https://stat.ethz.ch/pipermail/bioconductor/2009-August/029192.html Since I have no problems compiling my package on OpenSUSE11.1, MacOS X and WinXP, I assume that maybe some development package may not be installed? Do you know what might be the reason for the compilation error on Debian/Ubuntu? Which development headers/packages (glibc-headers, glibc-kernheaders??) need to be installed on Debian/Ubuntu?
