Static heap usage: 2129280 of 10648960, slop is 65536 -- 8320k wasted -- reset to 2194816k emacs: SHEAP_ADJUSTMENT needs to be modified to reduce memory waste!
You increased the heap size, but it's outside the fuzz range -- you are over it by about 8 MB. Emacs would run, but the problem is that the binary would be a lot larger than it needs to be. Under Cygwin, this is an issue because of the way that fork() works.
So what you have to do is increase SHEAP_ADJUSTMENT by enough that you end up in the comparison fuzz range.
actually writes sheap.c, so I edit the script to change the -620000 to:
+#ifdef HAVE_X_WINDOWS +#define SHEAP_ADJUSTMENT 2194816 /* XEmacs does this dynamically */ +#else +#define SHEAP_ADJUSTMENT 2194816 /* XEmacs does this dynamically */ +#endif
That's the correct thing to do. Edit the build script -- it patches the original emacs source for Cygwin.
What you want to do is look at the message you get after you compile:
Static heap usage: 2129280 of 10648960, slop is 65536 -- 8320k wasted -- reset to 2194816k
And figure out what to set SHEAP_ADJUSTMENT to based on how the first two numbers compare. The message says that you used 2129280 bytes out of 10648960 available, so decrease SHEAP_ADJUSTMENT by (10648960 - 2129280). SHEAP_ADJUSTMENT will be some negative number because the base heap size is 8 MB, and emacs doesn't need anywhere near that.
If it helps any, this piece of code hurts my head also -- I have no idea why it is set up to be so complicated. But it works! -- Joe Buehler
