Chucking out git head (git commit e3e392d from git://repo.or.cz/emacs.git) and doing a debug build as described below fails. The compilation looks for the non-existing file "chkmalloc.h". Here are the steps that I performed: ./autogen.sh ./configure --prefix=/usr/local/public-dev/ CPPFLAGS=-DDEBUG CFLAGS="-g -O0" make which fails as follows: gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I../src -I../lib -I/space/pub-repos/emacs.git/lib-src -I/space/pub-repos/emacs.git/lib-src/../src -I/space/pub-repos/emacs.git/lib-src/../lib -Wl,-znocombreloc -DDEBUG -g -O0 -DEMACS_NAME="\"GNU Emacs\"" \ -DVERSION="\"24.1.50\"" /space/pub-repos/emacs.git/lib-src/etags.c \ regex.o ../lib/libgnu.a -o etags /space/pub-repos/emacs.git/lib-src/etags.c:233:24: fatal error: chkmalloc.h: No such file or directory System is: Linux grower 3.3.2-6.fc16.i686 #1 SMP Sat Apr 21 13:23:12 UTC 2012 i686 i686 i386 GNU/Linux Regards, Dov
