嘗試編譯我使用GMP的代碼時出現此錯誤。有什麼辦法可以解決這個問題嗎?即時通訊使用Visual Studio 2010的命令提示符下進行編譯,這是我用過的命令:使用gmp編譯時出錯
CL testing.c gmp.lib
int main(void)
{
mpz_t a,b;
mpz_init(b);
mpz_init(a);
gmp_randstate_t rstate; // the problem arises when declaring this
}
testing.c
testing.c(9) : error C2275: 'gmp_randstate_t' : illegal use of this type as an e

你應該包括你的實際代碼。 –
爲什麼在cygwin下使用頭文件來編譯VC++? –
已添加源代碼,它被放置在cygwin文件夾中作爲臨時文件。它對代碼沒有影響,即使我把它移出了cygwin文件夾 – user1758596
