Made many suggested changes to the linux setup. Hopefully fixed bad section name bug. http://www.digitalmars.com/d/changelog.html

Hopefully fixed bad section name bug. http://www.digitalmars.com/d/changelog.htmlHi walter, Working better! But I still get one relocation error. It's completely different: ../../bin/dmd -I/home/john/dmd/src/phobos hello.d gcc hello.o -o hello -lphobos -lpthread -lm /usr/bin/ld: /usr/lib/gcc-lib/i586-pc-linux-gnu/3.2.2/../../../libphobos.a(gc.o): bad relocation section name `.rel.gnu.linkonce.t_d_new?' Otherwise still links to a runnable hello. As you can see, dmd still can't seem to access my dmd.conf even in /etc. If I don't include the -I switch, it just complains about not being able to find object.d again. I still don't know why. Nice to see the linker step integration in place. Thanks! later, John

Hope this helps. Is it possible to get the assembler output of dmd, or is there no intermediate assembly stage.

Yes, I did. I think this is a problem peculiar to my system (or me). Since I don't see anybody else reporting trouble with this.Otherwise still links to a runnable hello.

Closer... I get another linker warning (but hello still linked). /usr/bin/ld: ../dmd/lib/libphobos.a(gc.o): bad relocation section name `.rel.gnu.linkonce.t_d_new?' Again, I'm on Linux 7.3 with gcc version 29.6. I've also got gcc 3.3 (experimental) version on my machine. It shows the same behavior. BTW: Kudos on the linux port!

I tried to go a bit further than hello.d... I compiled d2html.d, using dmd -c d2html.d, and then gcc -o d2html d2html.o ~/dmd/lib/libphobos.a -lpthread -lm I'm using gcc 2.94. When I type "d2html hello.d", it crashes with a segv. Using ddd, I printed the backtrace: Bill Walter wrote:Made many suggested changes to the linux setup.

Last I remember, d2html didn't work because d2html.kwd doesn't exist. I'm just downloading 0.64 so I can't see if it's included or not (but I think not). However, I tried to compile it with 0.63 and I get "Error 42: Symbol Undefined __d_arraycatn". ------------------------- Carlos Santander --- Outgoing mail is certified Virus Free.

(dmd 0.64 on Win32)
void main() {
double d;
printf('%f',d.isnan);
}
I get: no property 'isnan' for type 'double'. The same happens when using
float or real, or for isinfinite, isnormal. I thought this was already
implemented.
By the way, maybe this a language (english) issue, but why this
inconsistency: float.infinity and float.isinfinite?

Ignore that second part I said. I was too tired to read well.
What I wanted to know is if I do
if (cond)
d=double.infinity
else
d=someOtherValue;
How do I check if d is infinity or not?
