Subject: Build against the system libsvm
I'm trying to package Algorithm::SVM for inclusion in Fedora. However, our packaging guidelines require that we don't use bundled libs, but instead link against the system ones. I'm attaching two patches: - Algorithm-SVM-0.13-Unbundle-libsvm.patch - Algorithm-SVM-0.13-Port-to-libsvm-3.0.patch The former is simply unbundling libsvm from Algorithm::SVM, and the latter ports it to the newer versions of libsvm (Fedora provides libsvm 3.12, so that's what I have to build against). I couldn't find any VCS for Algorithm::SVM, so the patches apply on the latest released tarball.

From c26aa307a3bfa74328e42061437c5467826f7ed3 Mon Sep 17 00:00:00 2001 From: Mathieu Bridon <bochecha@fedoraproject.org> Date: Tue, 21 Aug 2012 12:14:18 +0800 Subject: [PATCH 2/2] Port to libsvm >= 3.0 The libsvm README file states the following: - Function: void svm_free_and_destroy_model(struct svm_model **model_ptr_ptr); This function frees the memory used by a model and destroys the model structure. It is equivalent to svm_destroy_model, which is deprecated after version 3.0. --- bindings.cpp | 10 +++++----- 1 files changed, 5 insertions(+), 5 deletions(-) diff --git a/bindings.cpp b/bindings.cpp index 70cb3ab..af0b29f 100644 --- a/bindings.cpp +++ b/bindings.cpp @@ -166,7 +166,7 @@ int SVM::train(int retrain) { // Free any old model we have. if(model != NULL) { - svm_destroy_model(model); + svm_free_and_destroy_model(&model); model = NULL; } @@ -282,7 +282,7 @@ int SVM::loadModel(char *filename) { } if(model != NULL) { - svm_destroy_model(model); + svm_free_and_destroy_model(&model); model = NULL; } @@ -357,7 +357,7 @@ double SVM::crossValidate(int nfolds) { sumyy += y*y; sumvy += v*y; } - svm_destroy_model(submodel); + svm_free_and_destroy_model(&submodel); // cout << "Mean squared error = %g\n", error/(end-begin)); total_error += error; } else { @@ -368,7 +368,7 @@ double SVM::crossValidate(int nfolds) { double v = svm_predict(submodel,prob->x[j]); if(v == prob->y[j]) ++correct; } - svm_destroy_model(submodel); + svm_free_and_destroy_model(&submodel); //cout << "Accuracy = " << 100.0*correct/(end-begin) << " (" << //correct << "/" << (end-begin) << endl; total_correct += correct; @@ -423,6 +423,6 @@ int SVM::checkProbabilityModel() { SVM::~SVM() { if(x_space!=NULL) { free_x_space(); } - if(model != NULL) { svm_destroy_model(model); model=NULL; } + if(model != NULL) { svm_free_and_destroy_model(&model); model=NULL; } if(prob != NULL) { free(prob); prob=NULL; } } -- 1.7.1
