Re: [Bug-apl] Cygwin64 Build Errors

[Juergen Sauermann]

Hi Mike,

There is a line that reads:

   CXX_RDYNAMIC = "-rdynamic"

around line 16790 in thr top-level file named configure.

If you change that to:

   CXX_RDYNAMIC = ""
 
 and run ./configure again then the problem should disappear.

Alternatively you could also change configure.ac around line 42 accordingly, and then
run autoreconf followed by ./configure. However, that requires that the autotools are installed.

In older SVN versions I had a check in configure.ac that explicitly checked if the compiler accepts -rdynamic.
But then there were compilers that did accept it (returning an exit code of 0) and then issued a warning (which
was then breaking a make with -Wall -Werror.

If you have a test under your cygwin (= a command that has an exit code != 0 when -rdynamic is used)
then I can include it in ./configure.ac so that the patch above is no longer needed.

Just tried building GNU APL with 64-bit Cygwin on my Windows 10 Acer laptop.

It did not go well.
