私は$ ./configure && make dep && make && make installをしました。そして、私は、私はここでそれを見つけることができますlibpjproject libに検索する場合：

/usr$ find -iname "*libpjproject*" 
./local/lib/pkgconfig/libpjproject.pc 

はあなたの助けをありがとう！

エラーが見つかりました。私はMakefileで間違いを犯しました。
動作していない：

# If your application is in a file named myapp.cpp or myapp.c 
# this is the line you will need to build the binary. 
all: simple_pjsua 

myapp : simple_pjsua.c 
    $(CC) -o $@ $< `pkg-config --cflags --libs libpjproject` 

clean: 
    rm -f simple_pjsua.o simple_pjsua 

ワーキング：

# If your application is in a file named myapp.cpp or myapp.c 
# this is the line you will need to build the binary. 
all: simple_pjsua 

simple_pjsua: simple_pjsua.c 
    $(CC) -o $@ $< `pkg-config --cflags --libs libpjproject` 

clean: 
    rm -f simple_pjsua.o simple_pjsua 

を私はmyapp : simple_pjsua.c

simple_pjsua: simple_pjsua.cにを変更するのを忘れ
