Hi guys,
By coincidence, I was working on this aspect this afternoon.
In a nutshell, I'd like to use Emacs in text mode in certain
circumstances. In this case, I need command line tools.
My message is not directly related to SCons, but it presents some
similar experiences too. In the end, I describe a difficulty I found and
not yet solved.
1. directory layout
. I came from the Java world, specially using Maven, which basically
means we may have several source folders. At least, we have two folders:
one for main source files (many packages) and one for test files (many
packages too).
. There are usually folders reserved for "resources" (not code) which
usually needs to be packaged together to the code.
. We also usually build stuff in the "target" folder.
This is the directory layout:
src
main
x10
(main source code here)
resources
(lots of files/folders here)
test
x10
(test code here)
resources
(lots of files/folder here)
target
(generated binaries here)
2. In order to build my application, I've done the following:
$ cd target
$ x10c++ \
-o test \
-MAIN_CLASS=com.jquantlib.math.statistics.StatisticsTests \
`find ~/workspace-x10/xql-statistics/src/main/x10 \
-type f -name '*.x10' ` \
`find ~/workspace-x10/xql-statistics/src/test/x10 \
-type f -name '*.x10' ` \
3. Running the application
$ ./test
43
Great! It builds fine and the application executes :)
4. Difficulties
I said it works.
Well... it works only on my laptop, which is a i*86 thing
$ uname
Linux acer4150 2.6.35-22-generic #35-Ubuntu SMP Sat Oct 16 20:36:48 UTC
2010 i686 GNU/Linux
It does not run on my desktop, which is a x86_64 thing:
$ uname
Linux terra 2.6.32-5-amd64 #1 SMP Fri Oct 15 00:56:30 UTC 2010 x86_64
GNU/Linux
The error message is:
x10c++: /usr/bin/ld: skipping incompatible
/opt/JavaIDE/x10-2.1.0-linux-x86_64/lib/libgc.a when searching for -lgc
/usr/bin/ld: cannot find -lgc
collect2: ld returned 1 exit status
x10c++: Non-zero return code: 1
2 errors.
Looking at the build.xml script (intended to build the X10
distribution), I saw that there's no way to make difference between 32
bits and 64 bits on Linux, like this:
UNAME=`uname -smp | sed -e 's/ /,/g'`
FILE_SEP='/'; if [[ "$UNAME" = CYGWIN* ]]; then FILE_SEP='\\'; fi
PATH_SEP=':'; if [[ "$UNAME" = CYGWIN* ]]; then PATH_SEP=';'; fi
[ -n "$X10_PLATFORM" ] || \
case "$UNAME" in
CYGWIN*,i*86,*) export X10_PLATFORM='win32_x86';;
Linux,*86*,*) export X10_PLATFORM='linux_x86';;
Linux,ppc*,*) export X10_PLATFORM='linux_ppc';;
AIX,*,powerpc) export X10_PLATFORM='aix_ppc';;
Darwin,*,i*86) export X10_PLATFORM='macosx_x86';;
Darwin,*,powerpc) export X10_PLATFORM='macosx_ppc';;
SunOS,*,sparc) export X10_PLATFORM='sunos_sparc';;
FreeBSD,*64*,*) export X10_PLATFORM='freebsd_amd64';;
*) echo "Unrecognized platform: '$UNAME'"; exit 1;;
esac
# NOTE: the above assumes that Cygwin==win32 (probably valid)
Observe that "Linux,*86*,*" matches both Linux,i686 and Linux,x86_64 :(
I've tried to build X10 from sources and the error persists.
Just in case, I've downloaded again
x10-2.1.0_linux_x86_64.tgz
... and tried x10c++ again from it but it fails.
In fact, there's a possibility that my desktop is screwed up.
I admit I need to reinstall the entire box from scratch.
So, I'd like to hear from you guys if you are building on Linux x86_64
as expected, without troubles.
Just a final note:
x10-2.1.0_linux_x86_64.tgz suggests that it is a tar.gz file.
In fact, it is not!
$ file x10-2.1.0_linux_x86_64.tgz
x10-2.1.0_linux_x86_64.tgz: POSIX tar archive (GNU)
Thanks a lot :)
