Eu gostaria de empacotar meu software (em C) em um arquivo .deb , mas encontro algumas dificuldades. Seria legal se alguém pudesse me dar uma mão.
Deixe o código-fonte ser o seguinte exemplo de brinquedo:
#include <stdio.h>
#include <stdlib.h>
#include <lbfgs.h>
int main(void)
{
printf("liblbfgs will be used here!\n");
return 0;
}
No programa C acima, a biblioteca liblbfgs será usada. liblbfgs está disponível em repos. Eu escrevi o seguinte Makefile simples:
CXX=gcc
CFLAGS=-Wall -g
LIBS=-lm -llbfgs
OUTPUT=toypackage
$(OUTPUT): $(OUTPUT).o
$(CXX) -o $(OUTPUT) $(LIBS) $(OUTPUT).o
.PHONY: clean
clean:
rm -f *~ *.o
Se eu instalar a biblioteca via synaptic / apt-get ou compilando manualmente o código-fonte disponível e construindo o código acima, tudo ficará bem. Mas seria muito desejável evitar a instalação do liblbfgs primeiro. Por esse motivo, quero empacotar meu software em um arquivo .deb , no qual devo definir liblbfgs como dependência.
Eu crio uma pasta, digamos toypackage_1.0/ , onde eu armazeno o código fonte e o Makefile. Então eu comprimir este diretório como
tar czvf toypackage_1.0.orig.tar.gz toypackage-1.0/
Em seguida, corro dh_make da seguinte forma
$ cd toypackage-1.0/
$ dh_make
Type of package: single binary, indep binary, multiple binary, library, kernel module, kernel patch?

Done. Please edit the files in the debian/ subdirectory now. You should also
check that the toypackage Makefiles install into $DESTDIR and not in / .

liblbfgs will be used here!
vejo que o código foi criado corretamente, pois já instalei liblbfgs via apt-get .
Aqui estão minhas perguntas:
- E se eu não tiver instalado
liblbfgs antes? O que devo fazer para conseguir criar meu código corretamente?
- O que seria um Makefile significativo para meus propósitos? Você poderia me sugerir como alterá-lo usando
$DESTDIR$ para que os binários sejam armazenados em /usr/bin/ ?
