I've seen in the autoconf source that AC_TRY_EVAL should not be used: # AC_TRY_EVAL(VARIABLE) # --------------------- # Evaluate $VARIABLE, which should be a valid shell command. # The purpose of this macro is to write "configure:123: command line" # into config.log for every test run. # # The AC_TRY_EVAL and AC_TRY_COMMAND macros are dangerous and # undocumented, and should not be used. # They may be removed or their API changed in a future release. # Autoconf itself no longer uses these two macros; they are present # only for backward compatibility with previous versions of Autoconf. # Not every shell command will work due to problems with eval # and quoting, and the rules for exactly what does work are tricky. # Worse, due to double-expansion during evaluation, arbitrary unintended # shell commands could be executed in some situations. Thus this should also be seen as a libtool bug. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
