From: W. Trevor King Date: Mon, 1 Sep 2008 03:25:36 +0000 (-0400) Subject: Major rewrite of the build system/Makefile reorganized. X-Git-Tag: v0.5~12 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=7475d7b4e8b2ac2721a0dc173dadf3a3c74bf560;p=sawsim.git Major rewrite of the build system/Makefile reorganized. Almost everything got pushed out into subdirectories of the base `sawsim/' dir. All the versioned source got sent to `src'. Processing `sawsim.nw' generates C code, which is placed in `build' along with the odd bits of code not in the noweb file. Finally, we compile the code in `build' into executibles placed in `bin' and documents placed in `doc'. TODO: add appropriate commentary to `sawsim.nw'. Standardizing the Makefile also cut down on the module-specific code needed in the makefile, which should encourage better modulization. I hadn't been able to compile the checks in a while with the old system, and now they compile, but they don't pass the checks. Well, that's what checks are for ;), although in this case I suspect it's just that I've been ignoring the checks for a while and the code has moved on, leaving incompatible checks. Fixing the checks is the next order of business, so we can implement fast, pre-commit sanity-checks. --- diff --git a/README b/README index 32e9fb1..cc95311 100644 --- a/README +++ b/README @@ -3,7 +3,7 @@ Warning: also my noweb-training program.
