我用gcc和musl-gcc编译了这个GTK +示例应用程序。两者都生成了二进制文件，但是musl-gcc生成的二进制文件无法正确执行并显示了许多错误。
注意：我同时安装了musl-libc和libgtk3开发版。
注意：对于gcc和musl-gcc生成的二进制文件，ldd命令日志几乎完全相同。
GTK +示例应用程序：
#include <gtk/gtk.h>
static void activate (GtkApplication* app, gpointer user_data) {
GtkWidget *window;
window = gtk_application_window_new (app);
gtk_window_set_title (GTK_WINDOW (window), "Window");
gtk_window_set_default_size (GTK_WINDOW (window), 600, 600);
gtk_widget_show_all (window);
}
int main (int argc, char **argv) {
GtkApplication *app;
int status;
app = gtk_application_new ("org.gtk.example", G_APPLICATION_FLAGS_NONE);
g_signal_connect (app, "activate", G_CALLBACK (activate), NULL);
status = g_application_run (G_APPLICATION (app), argc, argv);
g_object_unref (app);
return status;
}

您不应手动传递编译参数。这就是pkg-config的用途，以及文档的Compiling GTK+ Applications部分中的建议。
所以您应该改为：
musl-gcc -g -Wall $(pkg-config --cflags gtk+-3.0) main.c -o main $(pkg-config --libs gtk+-3.0)
搜索../etc/ld-musl-$(ARCH).path Musl manual。
这里也是FAQ的摘录：
ldd在哪里？
musl的动态链接器内置了ldd功能。 创建一个从ld-musl- $ ARCH.so到/ bin / ldd的符号链接。如果动态 链接器以“ ldd”启动，它将检测到并打印 适当的DSO信息。
现在，musl似乎拥有不同的ldconfig，它不使用您的标准路径，这可以解释您的问题。您可以使用gcc的-L选项来解决该问题，并指定要在哪个目录中搜索库，但是更好的方法是学习链接程序和musl如何一起工作，以便编译器在正确的位置查找。 ldd毫无用处，它使用的是libc而不是musl的链接器配置。
