Hi I recommend to checkout the master branch and compile from there IT++. Here is the change I have made: --- a/itpp/base/random_dsfmt.h +++ b/itpp/base/random_dsfmt.h @@ -299,7 +299,7 @@ */ static void do_recursion(typename Context::w128_t *r, typename Context::w128_t *a, typename Context::w128_t *b, typename Context::w128_t *lung) { #if defined(__SSE2__) - const unsigned int SSE2_SHUFF = 0x1bU; +#define SSE2_SHUFF 0x1bU __m128i x = a->si; __m128i z = _mm_slli_epi64(x, SL1);

Hi, I have the same problem on Ubuntu 18.04. error: the last argument must be an 8-bit immediate __m128i y = _mm_shuffle_epi32(lung->si, SSE2_SHUFF); I'm a really bigineere in Linux, can you provid a link to the master branch with a bit more detail response? Thanks in advance. Alireza

Hi I have solved recently a similar issue that generated errors when IT++ is compiled on Ubuntu Bionic. You can find the relevant change here: https://sourceforge.net/p/itpp/git/ci/bb5c7e95f40e8fdb5c3f3d01a84bcbaf76f3676d/tree/itpp/base/random_dsfmt.h?diff=d425a09330ced7aa8192d695df9d38876df6c76d

Ok, so removing SSE2_SHUFF and replacing the entry with 0x1bU directly works. I will use this fix in Debian.
-
Replacing SSE_SHUFF with 27 solves the problem, though I don't know if that is right. This may also be connected: https://stackoverflow.com/questions/48726032/using-a-variable-to-index-a-simd-vector-with-mm256-extract-epi32-intrinsic

Hi, I'm trying to build it++ but am hitting the following compilation error. ~/itpp-4.3.1/itpp/base/random_dsfmt.h:306:18: error: the last argument must be an 8-bit immediate __m128i y = _mm_shuffle_epi32(lung->si, SSE2_SHUFF); Any ideas? Thanks, Greg

how to realize the convolutional funciton, should I use filter as conv function?
-
Hi IT++ is released under GPL licence and there were some discussions to adopt LGPL. If adopted, probably this will remain the only option for a commercial version. regards Bogdam
-
Hi all, is there a convolution function for vector? Or I should use filter as convolution function?

Guys, after a few days browsing the web, ...here i am. Trying to compile ITpp on windows 7 64bits using mingw492_32 ( from Qt 5.5 distri). A few months ago it was working fine, not anymore. sh configure --enable-static --disable-shared -with-blas=blas --with-lapack=lapack --with-fft=fftw3 lapack and blas are found...looks liek it finds FFTW3 but not fftw3.h...but i added path to System path. ...any idea what's going on ? thanks, Output: configure:26046: result: no configure:26190: checking for zfft1dx...

Good afternoon! Does anyone have an example of the LDPC decoder being used to support DVB-S2? I'm working on a soft demod for DVB-S2 and if someone else has already stood up/tested the LDPC codec, this'd be very useful... Best Regards, /jw

Just for information, what would be the price of a limited commercial version of IT++ ? Best regards, Vincent

Hi From command line use cmake .. -DITPP_EXCEPTIONS=on or in cmake-gui define a new variable ITPP_EXCEPTIONS of type bool and init with true. This should at least put in config.h a #define ITPP_EXCEPTIONS regards Bogdan

IT++ has a large collection of utilities, which might be an overkill for many cases where all that the user needs is: Vec<T>, Mat<T>, random numbers, and overloaded operators. In other words, all that the user ever needs is #include<itpp/itbase.h> for all his applications and nothing more. In this case, I find a precompiled header an overkill, because he can compile all those IT++ routines along with his program without any significant/noticeable additional delay. In some cases, user may be willing...

IT++ has a large collection of utilities, which might be an overkill for many cases where only basic linear algebra and RNG utilities are desired. (mainly Vec<T>, Mat<T>, random numbers, and overloaded operators) In other words, the user needs to include itpp/itbase.h for all his applications and nothing else. In this case, I find expecting a precompiled header is an overkill. In my expectation, by simply having: 1. #include of a set of .h and .cpp files of IT++, in the source (maybe, replacing itpp/itbase.h)...

There is a new C++ signal processing library called SigPack: http://sigpack.sourceforge.net/ https://sourceforge.net/projects/sigpack/ SigPack is actively developed, while IT++ seems to be stagnant these days.
