Erro de compilação

Question

Oi eu preciso executar alguns testes com um kit de ferramentas CP ABE que eu encontrei , eu sou um total novato do Linux, eu comecei a usar por alguns dias, por favor, tenha paciência comigo. Eu encontrei este vídeo tutorial que foi bastante útil e me fez instalar: -m4 linguagem de processamento de macros biblioteca -gmp biblioteca -pbc -libcrypt -libssl -libglib2.0 biblioteca de libbswabe

Eu segui todas as passagens do vídeo, mas quando eu tenho que compilar o pacote cpabe após o make este erro aparece (embora não pareça o caso no tutorial)

Abra o Makefile e encontre as seguintes linhas:

LDFLAGS = -O3 -Wall \
        -lglib-2.0   \
        -Wl,-rpath /usr/local/lib -lgmp \
        -Wl,-rpath /usr/local/lib -lpbc \
        -lbswabe \
        -lcrypto -lcrypto

Agora basta adicionar um -lgmp ao lado de -lcrypto e será bem-sucedido

LDFLAGS = -O3 -Wall \
        -lglib-2.0   \
        -Wl,-rpath /usr/local/lib -lgmp \
        -Wl,-rpath /usr/local/lib -lpbc \
        -lbswabe \
        -lcrypto -lcrypto -lgmp
