Hi, I'm trying to build Gambit on the current Debian Stable (buster), and am getting stuck on some errors. This is with the following: uname -v -m -o #1 SMP Debian 4.19.67-2+deb10u2 (2019-11-11) x86_64 GNU/Linux gcc --version gcc (Debian 8.3.0-6) 8.3.0 I did: git clone https://github.com/gambit/gambit cd gambit ./configure make and got the following: [...] gcc -O3 -Wno-unused -Wno-write-strings -Wdisabled-optimization -fwrapv -fno-strict-aliasing -fno-trapping-math -fno-math-errno -fschedule-insns2 -fomit-frame-pointer -fPIC -fno-common -mpc64 -I"../include" -c -o os_files.o -I. -DHAVE_CONFIG_H -D___GAMBITDIR="\"/usr/local/Gambit\"" -D___GAMBITDIR_USERLIB="\"~/.gambit_userlib\"" -D___GAMBITDIR_INSTLIB="\"~~userlib\"" -D___SYS_TYPE_CPU="\"x86_64\"" -D___SYS_TYPE_VENDOR="\"pc\"" -D___SYS_TYPE_OS="\"linux-gnu\"" -D___CONFIGURE_COMMAND="\"./configure"\" -D___OBJ_EXTENSION="\".o\"" -D___EXE_EXTENSION="\"\"" -D___BAT_EXTENSION="\"\"" -D___PRIMAL os_files.c -D___LIBRARY os_files.c: In function ‘rename_long_path’: os_files.c:877:36: error: ‘RENAME_NOREPLACE’ undeclared (first use in this function); did you mean ‘MAP_FIXED_NOREPLACE’? if (!replace) flags |= RENAME_NOREPLACE; ^~~~~~~~~~~~~~~~ MAP_FIXED_NOREPLACE os_files.c:877:36: note: each undeclared identifier is reported only once for each function it appears in os_files.c:878:22: warning: implicit declaration of function ‘renameat2’; did you mean ‘renameat’?
