Not true. automake does not have explicit support for building programs with the host compiler when cross-compiling, but I have done this successfully in the past when I needed precisely to build a program on the host when cross compiling, using binutils's BFD_CC_FOR_BUILD macro. It's a pity some version of this macro isn't in autoconf, or even autoconf-archive; I shall do the latter. This illustrates a weirdness of autotools: poor support for installing interpreted languages, and also conversely for build-time compiled programs. > I though of perl, but (A), i don't like slow tools, Purlease... > (B), unidata.tab.c > is 5.6MBytes and 450k lines long, and? > (C), i find making build-programs > in C much more concise than scripting and i can debug it in ddd/gdb. This is interesting, as it doesn't match mine or commonly-reported experience (translating my build-time programs from C to Perl made them shorter, easier to read and fix, and no slower to run, although I wasn't doing more than grepping 15k lines of C and writing some of it back out again). -- http://rrt.sc3d.org
