Question about which tools to use, bugs, the best way to implement a function, etc should go here. Don't forget to see if your question is answered in the wiki first! When in doubt post here.
Has anyone else dealt with porting https://github.com/unicode-org/icu? The stuff inside of icu4c/source/data builds a super huge icudt72l_dat.S, that when statically linked into my applications, causes the binaries to grow by 43MB!
It's read inside of source/common/udata.c in doLoadFromCommonData and openCommonData via the macro U_ICUDATA_ENTRY_POINT. I noticed the macro ICU_DATA_DIR_WINDOWS, but I'm going to have to dig into it a little more to see if I can move it to a file. And perhaps implement processes sharing the memory of files.
Unfortunately I don't have support for shared libraries. For now, I'd like to load it from a file. I'll change the U_ICUDATA_ENTRY_POINT macro to be a pointer to a function that lazily loads the data file into memory, then returns a pointer to it.
(My microkernel does support shared memory between processes. For large read-only data files, perhaps I could make a service (maybe the VFS) that reads files into shared memory. I'll have to update my shared memory to support one-writer/multiple-readers.)
I got it to build with the archive file. (I use a custom build system so I'm unravelling what the make rules do and reimplementing it in my system. I had to link in stubdata but then set the macro to the directory where I put the generated .dat file.)
I ported icu because it's a dependency of Skia. I actually have Skia building and drawing my UI widgets now, except text. I have an issue with fontconfig not being able to parse my fonts.conf.
