make faild at "gettext-runtime/intl/plural.c"

[川原智和]

I'm tring to build gettext  on macOS catalina from source (cloned from savannah).

./autogen.sh and ./configure  go through well, but make will stop with below message.

libtool: compile:  gcc -DHAVE_CONFIG_H -I. -I../../../gettext-runtime/intl -I.. -DLOCALEDIR=\"/usr/local/git/share/locale\" -DLOCALE_ALIAS_PATH=\"\" -DLIBDIR=\"/usr/local/git/lib\" -DBUILDING_LIBINTL -DBUILDING_DLL -DIN_LIBINTL -DENABLE_RELOCATABLE=1 -DIN_LIBRARY -DINSTALLDIR=\"/usr/local/git/lib\" -DNO_XMALLOC -Dset_relocation_prefix=libintl_set_relocation_prefix -Drelocate=libintl_relocate -Drelocate2=libintl_relocate2 -DDEPENDS_ON_LIBICONV=1 -fvisibility=hidden -g -O2 -c ../../../gettext-runtime/intl/plural.c  -fno-common -DPIC -o .libs/plural.o

clang: error: no such file or directory: '../../../gettext-runtime/intl/plural.c'

clang: error: no input files

make[5]: *** [plural.lo] Error 1

make[4]: *** [all] Error 2

make[3]: *** [all-recursive] Error 1

make[2]: *** [all] Error 2

make[1]: *** [all-recursive] Error 1

make: *** [all] Error 2

How can I fix it? (And I want not to depend on homebrew.)
