Now I got another, where has sys_errlist.h gone, and how do I resolve this: ***************** /bin/sh ../../../libtool --tag=CC --mode=compile x86_64-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I. -I../../../src/include -I../../../src/include -I../../../src/frontend -I/usr/include -shared -O2pc libtool: compile: x86_64-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I. -I../../../src/include -I../../../src/include -I../../../src/frontend -I/usr/include -O2 -pipe -I/usr/include -fopenmp -c graf.c -fCo In file included from gnuplot.c:13:0: gnuplot.c: In function ?<80><98>ft_gnuplot?<80><99>: ../../../src/include/ngspice/ngspice.h:284:57: error: ?<80><98>sys_errlist?<80><99> undeclared (first use in this function) #define perror(string) fprintf(stderr,"%s: %s\n",string,sys_errlist[errno]) ^ gnuplot.c:129:9: note: in expansion of macro ?<80><98>perror?<80><99> perror(filename); ^~~~~~ ../../../src/include/ngspice/ngspice.h:284:57: note: each undeclared identifier is reported only once for each function it appears in #define perror(string) fprintf(stderr,"%s: %s\n",string,sys_errlist[errno]) ^ gnuplot.c:129:9: note: in expansion of macro ?<80><98>perror?<80><99> perror(filename); ^~~~~~ gnuplot.c: In function ?<80><98>ft_writesimple?<80><99>: ../../../src/include/ngspice/ngspice.h:284:57: error: ?<80><98>sys_errlist?<80><99> undeclared (first use in this function) #define perror(string) fprintf(stderr,"%s: %s\n",string,sys_errlist[errno]) ^ gnuplot.c:360:9: note: in expansion of macro ?<80><98>perror?<80><99> perror(filename); ^~~~~~ make[3]: *** [Makefile:452: gnuplot.lo] Error 1 make[3]: *** Waiting for unfinished jobs.... make[3]: Leaving directory '/Net/gentoo/tmpdir/portage/sci-electronics/ngspice-27-r1/work/ngspice-27-binaries/src/frontend/plotting' make[2]: *** [Makefile:827: all-recursive] Error 1 make[2]: Leaving directory '/Net/gentoo/tmpdir/portage/sci-electronics/ngspice-27-r1/work/ngspice-27-binaries/src/frontend' make[1]: *** [Makefile:1387: all-recursive] Error 1 make[1]: Leaving directory '/Net/gentoo/tmpdir/portage/sci-electronics/ngspice-27-r1/work/ngspice-27-binaries/src' make: *** [Makefile:440: all-recursive] Error 1 ***************** Since the header file is the same as last time: # md5sum work/ngspice-27/src/include/ngspice/ngspice.h /usr/include/ngspice/ngspice.h e695c3d756b1b934563779766bfd7881 work/ngspice-27/src/include/ngspice/ngspice.h e695c3d756b1b934563779766bfd7881 /usr/include/ngspice/ngspice.h there must be something else at play here. $ find /usr/include -type f -name \*.h | xargs grep sys_errlist /usr/include/X11/Xw32defs.h:# define sys_errlist _sys_errlist /usr/include/nspr/prerror.h:** (sys_errlist); this allows errno values to be used directly in the /usr/include/schily/errno.h:extern char *sys_errlist[]; /usr/include/ngspice/ngspice.h:#define perror(string) fprintf(stderr,"%s: %s\n",string,sys_errlist[errno]) /usr/include/ngspice/ngspice.h:#define perror(string) fprintf(stderr, "%s: %s\n", string, sys_errlist[errno]) $ grep sys_errlist.h /var/db/pkg/*/*/CONTENTS $ I have a crosscompiler that has sys_errlist[]: /home/local/gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf/arm-linux-gnueabihf/libc/usr/include/stdio.h:#include <bits/sys_errlist.h> $ tail -7 /home/local/gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf/arm-linux-gnueabihf/libc/usr/include/bits/sys_errlist.h extern int sys_nerr; extern const char *const sys_errlist[]; #endif #ifdef __USE_GNU extern int _sys_nerr; extern const char *const _sys_errlist[]; #endif Regards, /Karl Hammar
