> I have also tried to build maxima using gcl but then the configure
script complains about the missing ansi support in the gcl version which
resided in the ubuntu repository...
Turns out, and this is probably true going back to even karmic, that gcl
*did* come with ansi-cl support... the readme says as much, but you need
environment variable GCL_ANSI to be defined (AND EXPORTED) in order for
ansi-cl to be available.
themusicgod1@eva1:~$ export GCL_ANSI=""
themusicgod1@eva1:~$ gcl -batch -eval '#+ansi-cl (format t
"MAXIMA_GCL_ANSI_TEST_SUCCESS~%") #-ansi-cl (format t
"MAXIMA_GCL_ANSI_TEST_FAILURE~%")' -eval '(si::bye)'
MAXIMA_GCL_ANSI_TEST_FAILURE
themusicgod1@eva1:~$ export GCL_ANSI="true"
themusicgod1@eva1:~$ gcl -batch -eval '#+ansi-cl (format t
"MAXIMA_GCL_ANSI_TEST_SUCCESS~%") #-ansi-cl (format t
"MAXIMA_GCL_ANSI_TEST_FAILURE~%")' -eval '(si::bye)'
MAXIMA_GCL_ANSI_TEST_SUCCESS
maxima does build (at least for me) with GCL_ANSI defined and set to
true in the above manner, even when I compile maxima with gcl and then
remove gcl from my system
Anyway. The aforementioned debian bug suggests this is a kernel
security setting issue:
"Greetings! Your kernel is not allowing pages to be marked executable,
or maybe writable:
if(mprotect(pagetochar(pbeg),n*PAGESIZE,
(writable & SGC_WRITABLE ? PROT_READ_WRITE_EXEC :
PROT_READ_EXEC)))
FEerror("Couldn't protect",0);"
Camm Maguire asked for more details why...8 years ago. Without details
on why it's kind of hard to progress on this. Marking incomplete.
** Changed in: maxima (Ubuntu)
Status: Confirmed => Incomplete
