hello clinton,
may I ask what you are *really* trying to achieve? Personally, I would like to depracate to prefix a config.h file in place, even more if you would really install it along with your library - I've seen to many include-order conflicts for this case, so please don't do that. Secondly, if I read your post well, then you try to modify a file, but not twice, but want to rerun it. Am I confused? Well, might be. Anyway, I don't expect things to be easy, for the case that the input and output file are in the same position. Thirdly, you didn't mention that the ac-macro has a few optional arguments, one being input-file, the other being output-file, which you didn't mention again. What's wrong with that, and if it is not sufficient, why didn't you contact me? Fourthly, so you try to add it to ac_config_commands, hey I like that, I did not quite bother so far to add the script to config.headers, so that the prefixing can be run automatically as a dependency of a reconf. But first, let's sort things out what you're really trying to achieve. cheers, -- guido Es schrieb Clinton Roy: > > Hello all, I'm trying to mangle a config.h for a shared library, we'd > like all the definitions in it to have the same prefix. > > I've tried using AC_CREATE_PREFIX_CONFIG_H from > http://www.gnu.org/software/ac-archive/Miscellaneous/ac_create_prefix_config_h.html > > but it doesn't work so well when the input and the output file are the > same. > > I've got a simple sed command followed by a mv to do the prefixing > for me, but I'm not sure how to get these commands run after config.h > is created; AC_CONFIG_COMMANDS comes close, but config.status doesn't > always run my commands, this is probably because I am using the wrong > tag, but since I can't use the tag of config.h I'm stuck. > > I've also tried AC_CONFIG_HEADERS, but automake complains: > automake requires `AM_CONFIG_HEADER', not `AC_CONFIG_HEADER' > > Any help appreciated. > > autoconf 2.52 > automake 1.5d > > -- > Clinton Roy > > Meetings - ``Try, or no try; there is no do.'' -- guido http://freespace.sf.net/guidod GCS/E/S/P C++/++++$ ULHS L++w- N++@ d(+-) s+a- r+@>+++ y++ 5++X- (geekcode)
