ah yes, should've read this mail before i answered the last one.

hmm, günter, what is the suggested way to handle such things with 
configure ?

/usr/local is just the default installation path of configure; you 
should be able to set it with a flag to configure (but it is only of 
importance, if you want to install Gem via "make install"; otherwise you 
are safe by ignoring it)

well, again: configure should figure out, that "-shared  ..." is 
invalid. for bundle-loader i have obviously used the wrong options.

aha.
reading the man-page for g++ it says:
"If you use multiple -O options, with or without level numbers, the last 
such option is the one that is effective."

and on "-Os" it says that it turns _off_ optimizazions that might 
increase size.

so to be on the safe side, it would probably be good to use "-Os -O3" (?)

ok.


i just noticed that our G4 is online and did some testing myself with 
the new configure thing.
i hopefully fixed a lot of issues you 2 were having.
i'll check them in in a second.
finally it compiled, linked and stripped cleanly.
unfortunately, i was having a break during compilation and when i cam 
back from dinner, the G4 was turned off. (it is physically located in 
one of our studios, and i guess it was too loud for the people working 
in there)
so i don't know whether pd is able to load the produced library (and of 
course i have no idea, whether Gem will work once it is loaded)


ah, one last thing:
i have also moved the content of macos_math.{h,cpp} into Base/GemMath.h.
so in future we would just have to include "Base/GemMath.h" as opposed 
to <math.h> and the float vs. double thing will get corrected automatically.
