I'm running configure with the following flags: | ./configure CC=gcc-6
The error I get while building: | make[1]: Entering directory '/home/dualbus/local/src/gnu/bash/lib/malloc' | gcc-6 -I. -I../.. -I../.. -I../../include -I../../lib -DHAVE_CONFIG_H -DSHELL -Wall -g -ggdb -O0 -Wno-parentheses -Wno-format-security -DRCHECK -Dbotch=programming_error -DMALLOC_DEBUG -c malloc.c | malloc.c: In function ‘xsplit’: | malloc.c:472:21: warning: unused variable ‘split_max’ [-Wunused-variable] | int nbuck, nblks, split_max; | ^~~~~~~~~ | malloc.c: In function ‘posix_memalign’: | malloc.c:1143:12: error: ‘EINVAL’ undeclared (first use in this function) | return EINVAL; | ^~~~~~ | malloc.c:1143:12: note: each undeclared identifier is reported only once for each function it appears in | malloc.c:1153:10: error: ‘ENOMEM’ undeclared (first use in this function) | return ENOMEM; | ^~~~~~ | malloc.c:1154:1: warning: control reaches end of non-void function [-Wreturn-type] | } | ^ | At top level: | malloc.c:669:1: warning: ‘malloc_debug_dummy’ defined but not used [-Wunused-function] | malloc_debug_dummy () | ^~~~~~~~~~~~~~~~~~ | Makefile:62: recipe for target 'malloc.o' failed | make[1]: *** [malloc.o] Error 1 | make[1]: Leaving directory '/home/dualbus/local/src/gnu/bash/lib/malloc' | Makefile:399: recipe for target 'lib/malloc/libmalloc.a' failed | make: *** [lib/malloc/libmalloc.a] Error 1 This is fixed by adding an errno.h include inside lib/malloc/malloc.c -- Eduardo Bustamante https://dualbus.me/
