Hi Denis. You should build your library using g++ instead of ld. The reason is that g++ links additional object files that are essencial for a library to work well (namely, crtbegin.o, crtend.o, crti.o, and crtn.o). Try: g++ -fPIC -I[jdk-root]/include -I[jdk-root]/include/genunix Load.cc Load.

Hi. I erased the original mail asking about arbitrary precision calculations in Java so I couldn't use the right subject... Take a look at http://math.nist.gov/javanumerics. Maybe you could find something useful in the "Libraries" section. Hope it can help. Best regards, -- Cassino

Hi Jeremy. I guess your problem is the size of long. It has 64 bits and not only the 32 bits you are using. If you change your program to: n = 0xf0f0f0f0L; it should work. If you don't do this, higher bits get set to 1 and the output of your program is right (although it does not show these hi

Hi Jeremy. Maybe your problem is the long type size: it has 64 bits, not only the 32 bits you are using. If you change your program to: n = 0xf0f0f0f0L; You'll get the expected result. When you don't do it, higher bits are set to 1 and the output seems wrong (only seems). Try using: System.o

JDK + Libraries

Hello there! I have some C++ code that I put in a dynamic library and I want to use it from Java. Since JDK does not allow me to load two different libraries that depend on each other, I implemented a native method that does the following: 1) Loads libstdc++.so 2) Loads my library 3) Performs s

loadLibrary

1998-07-28 Thread Carlos Cassino
Hi. I'm using loadLibrary in jdk1.1.6-v2-glibc but it does not work as I expected. The problem is: if I load library A and then load library B, it issues an error if B depends on A, that is, if B references any symbol from A. Is that right? I really need this feature, is there any workaround? I
