unable to compile freeverb3vst (2017-05-11 02:25 by mrbumpy409 #79820)
I checked the code out using mercurial and made a small change that I need for my use (disable MIDI input for impulser2). Based on automake warnings, I replaced all "INCLUDES" instances in each "Makefile.am" with "AM_CPPFLAGS".
Unfortunately, when I attempt to compile under Ubuntu (16.04/14.04/12.04) + mingw-w64, the autoconf step generates the following errors:
configure.ac:59: error: possibly undefined macro: AC_C99_FUNC_LRINT
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
configure.ac:60: error: possibly undefined macro: AC_C99_FUNC_LRINTF
configure.ac:64: error: possibly undefined macro: AC_C_CLIP_MODE
configure.ac:81: error: possibly undefined macro: AC_C99_FLEXIBLE_ARRAY
configure.ac:193: error: possibly undefined macro: AC_C_FIND_ENDIAN
Later, configure complains:
./configure: line 18086: AC_C99_FUNC_LRINT: command not found
./configure: line 18087: AC_C99_FUNC_LRINTF: command not found
./configure: line 18097: AC_C_CLIP_MODE: command not found
checking whether S_IRGRP is declared... yes
./configure: line 18137: AC_C99_FLEXIBLE_ARRAY: command not found
configure: WARNING: *** This compiler does not support the 1999 ISO C Standard ***
configure: WARNING: *** feature known as the flexible array struct member. ***
I cannot find any useful info about this online. What should I do?
